Custom Tool Selection breaking on input, any ideas how to fix?

Hey, I'm making an FPS and I've gotten rid of the default backpack in favour of weapons slots corresponding to keys on the Number Line. My Idea is that if you press 1 you select your primary and if you press 2 you select your sidearm; alternatively, if you press said key with the weapon already selected you can unequip to move faster.

Unfortunately, my script breaks upon two "if" statements

if inputObject.KeyCode == Enum.KeyCode.One then
---CODE for PRIMARY
elseif inputObject.KeyCode == Enum.KeyCode.Two then
--CODE for SIDEARM
else ---Attempt at nil debounce
end

and

if player.ClassInfo.ClassValue.Value == 1 then
---EQUIP PRIMARY
else ---Attempt at nil debounce
end

If anyone can help me I would really appreciate it, I'm new to lua but I understanding programming reasonably well so I know it works if I only have one Input but I would rather use one consilidated system for weapon selection. Thanks

-- Make variables for the local player and ContextActionService
local player = game.Players.LocalPlayer
equippedPri = true
equippedSec = false

function onKeyPress(inputObject, gameProcessedEvent)
--PRIMARY
	if inputObject.KeyCode == Enum.KeyCode.One then	
		if player.ClassInfo.ClassValue.Value == 1 then
			if game.Players.LocalPlayer.Team == "BLUFOR" then
				if equippedPri == false then	
					player.Character.Humanoid:UnequipTools()
					local gun = player.Backpack["M32 Carbine w/ Holo Sight"]
					player.Character.Humanoid:EquipTool(gun)
					equippedPri = true
					equippedSec = false
				elseif equippedPri == true then
					local gun = player.Character["M32 Carbine w/ Holo Sight"]
					player.Character.Humanoid:UnequipTools()
					equippedPri = false
				end		
			end
		else --Attempt at nil debounce
		end	
--SECONDARY
	elseif inputObject.KeyCode == Enum.KeyCode.Two then	
		if game.Players.LocalPlayer.Team == "BLUFOR" then
			if equippedSec == false then
				player.Character.Humanoid:UnequipTools()	
				local gun = player.Backpack["P83"]
				player.Character.Humanoid:EquipTool(gun)
				equippedPri = false
				equippedSec = true
			elseif equippedSec == true then
				local gun = player.Character["P83"]

				player.Character.Humanoid:UnequipTools()
				equippedSec = false
			end			
		end
	else	 --Attempt at nil debounce
	end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

I managed to fix it myself, this will limit the player to two weapons but it will work no matter what weapons the player has.

-- WEAPON VARIABLES
equippedPri = true
equippedSec = false

function onKeyPress(inputObject, gameProcessedEvent)
--PRIMARY
	if inputObject.KeyCode == Enum.KeyCode.One then	
		if equippedPri == false then -- if Secondary equipped
			local primary = game.Players.LocalPlayer.Backpack
			local gun1 = primary:FindFirstChildOfClass("Tool")	
			game.Players.LocalPlayer.Character.Humanoid:UnequipTools()
			game.Players.LocalPlayer.Character.Humanoid:EquipTool(gun1)
			equippedPri = true
			equippedSec = false
		elseif equippedPri == true then -- redundancy
			print("AlreadyEquipped")
		end
	end	
--SECONDARY
	if inputObject.KeyCode == Enum.KeyCode.Two then	
		if equippedSec == false then -- if Primary equipped
			local secondary = game.Players.LocalPlayer.Backpack
			local gun = secondary:FindFirstChildOfClass("Tool")
			game.Players.LocalPlayer.Character.Humanoid:UnequipTools()
			game.Players.LocalPlayer.Character.Humanoid:EquipTool(gun)
			equippedPri = false
			equippedSec = true
		elseif equippedSec == true then -- redundancy
			print("AlreadyEquipped")		
		end
	end
end
