How do I make the script detect the chat?

This sounds like a stupid question but it's not.

I'm making a simulator with a pet equip system with chat and for some reason it does not detect the chat when it used to.

This is the local script:

local peton = false
local player = game.Players.LocalPlayer
player.Chatted:Connect(function(chat)
	if chat == "/petequip" then
		peton = true
		game.StarterGui:SetCore("ChatMakeSystemMessage",{
			Text = "Now say the pet you want to equip. Make sure to captialize the first letter!";
			Color = Color3.new(1, 1, 1);
			Font = Enum.Font.Arcade;
		})
		player.Chatted:Connect(function(chat)
			if peton == true then
				peton = false
				local id = "0"
				if chat == "Doggo" then
					id = "1"
					game.Workspace.PetEquip.Remote:FireServer(id)
				else
					if chat == "Kitty" then
						id = "2"
						game.Workspace.PetEquip.Remote:FireServer(id)
					else
						if chat == "Bunny" then
							id = "3"
							game.Workspace.PetEquip.Remote:FireServer(id)
						else
							if chat == "Beary" then
								id = "4"
								game.Workspace.PetEquip.Remote:FireServer(id)
							else
								if chat == "Birdy" then
									id = "5"
									game.Workspace.PetEquip.Remote:FireServer(id)
								else
									if chat == "Neon Orb" then
										id = "6"
										game.Workspace.PetEquip.Remote:FireServer(id)
									else
										if chat == "Neon Chaos Elemental" then
											id = "7"
											game.Workspace.PetEquip.Remote:FireServer(id)
										else
											if chat == "Stone" then
												id = "8"
												game.Workspace.PetEquip.Remote:FireServer(id)
											else
												if chat == "Coal" then
													id = "9"
													game.Workspace.PetEquip.Remote:FireServer(id)
												else
													if chat == "Iron" then
														id = "10"
														game.Workspace.PetEquip.Remote:FireServer(id)
													else
														if chat == "Amethyst" then
															id = "11"
															game.Workspace.PetEquip.Remote:FireServer(id)
														else
															if chat == "Sapphire" then
																id = "12"
																game.Workspace.PetEquip.Remote:FireServer(id)
															else
																if chat == "Ruby" then
																	id = "13"
																	game.Workspace.PetEquip.Remote:FireServer(id)
																else
																	if chat == "Gold" then
																		id = "14"
																		game.Workspace.PetEquip.Remote:FireServer(id)
																	else
																		if chat == "Diamond" then
																			id = "15"
																			game.Workspace.PetEquip.Remote:FireServer(id)
																		else
																			if chat == "Uranium" then
																				id = "16"
																				game.Workspace.PetEquip.Remote:FireServer(id)
																			else
																				if chat == "Flame Doggo" then
																					id = "17"
																					game.Workspace.PetEquip.Remote:FireServer(id)
																				else
																					if chat == "Flame Kitty" then
																						id = "18"
																						game.Workspace.PetEquip.Remote:FireServer(id)
																					else
																						if chat == "Flame Bunny" then
																							id = "19"
																							game.Workspace.PetEquip.Remote:FireServer(id)
																							if chat == "Flame Beary" then
																								id = "20"
																								game.Workspace.PetEquip.Remote:FireServer(id)
																							else
																								if chat == "Flame Birdy" then
																									id = "21"
																									game.Workspace.PetEquip.Remote:FireServer(id)
																								else
																									if chat == "Fire Orb" then
																										id = "22"
																										game.Workspace.PetEquip.Remote:FireServer(id)

																													print("Detect")

																													game.Workspace.PetEquip.Remote:FireServer(id)
																												end
																											end
																										end
																									end
																								end
																							end
																						end
																					end
																				end
																			end
																		end
																	end
																end
															end
														end

Hello CandyWreckEpicness!

Looking over your code, I would strongly recommend you change how this works; it is very cluttered and doesn't seem intuitive.

I would recommend you separate parts of the message and use one of the message parts to index an array containing information stored about the pets and or whatever you need to store.

Example:

local Players = game:GetPlayers()

local player = Players.LocalPlayer
local command = "/petequip"

local petInfo = {
	doggo = {
		id = 1
		-- Any other data...
	},
}

player.Chatted:Connect(function(msg)
	msg = msg:split(" ") -- This will split the message every space
	if (msg[1]:lower() == command) then
		local pet = petInfo[msg[2]:lower()
		if (not pet) then 
			return
		end
		-- FireServer:(pet.id)
	end
end

This is a very rough model of what I was trying to explain; let me know if this helps at all!

I figured out an easy way myself.

player.Chatted:Connect(function(chat)
	if chat == "/petequip" then
		peton = true
		game.StarterGui:SetCore("ChatMakeSystemMessage",{
			Text = "Now say the pet you want to equip. Make sure to captialize the first letter!";
			Color = Color3.new(1, 1, 1);
			Font = Enum.Font.Arcade;
		})
		player.Chatted:Connect(function(chat)
			if peton == true then
				peton = false
				local id = "0"
				if chat == "Doggo" then
					id = "1"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Kitty" then
					id = "2"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Bunny" then
					id = "3"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Beary" then
					id = "4"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Birdy" then
					id = "5"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Neon Orb" then
					id = "6"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Neon Chaos Elemental" then
					id = "7"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Stone" then
					id = "8"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Coal" then
					id = "9"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Iron" then
					id = "10"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Amethyst" then
					id = "11"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Sapphire" then
					id = "12"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Ruby" then
					id = "13"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Gold" then
					id = "14"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Diamond" then
					id = "15"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Uranium" then
					id = "16"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Flame Doggo" then
					id = "17"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Flame Kitty" then
					id = "18"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Flame Bunny" then
					id = "19"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Flame Beary" then
					id = "20"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Flame Birdy" then
					id = "21"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Fire Orb" then
					id = "22"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Living Flames" then
					id = "23"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Inferno Torch" then
					id = "24"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
				if chat == "Fire Demon" then
					id = "25"
					game.Workspace.PetEquip.Remote:FireServer(id)
				end
