Why won't this gui morph script work?

Hello! I'm new to this site and i've came here after I can't understand why this won't work. Basically, what my script does is that when you click a screengui, the script will morph you into a set morph within the gui's parent. Maybe this screenshot will explain it better.

The gui itself looks like this. The gui that is supposed to morph the character is the archer gui.

The code that morphs the player is

wait()


-- Variables

local sp = script.Parent
local reset = sp.ResetAppearance

local debounce = true


-- Functions

script.Parent.MouseButton1Click:connect(function(touched)
	local body = sp.PartFolder:GetChildren()
	local player = game.Players:GetPlayerFromCharacter(script.Parent)
	if player and debounce == true then
		debounce = false
		if reset.Value == true then
			local charparts = touched.Parent:GetChildren()
			for i,v in pairs(charparts) do
				if v:IsA("Hat") or v:IsA("Model") then
					v:Destroy()
				elseif v:IsA("BasePart") then
					v.Transparency = 1
					for i2,v2 in pairs(v:GetChildren()) do
						if v2:IsA("Decal") then
							v2:Destroy()
						end
					end
				end
			end
		end
		
		for i,v in pairs(body) do
			local check = true
			
			local checkchar = touched.Parent:GetChildren()
			local checkparts = v:GetChildren()
			
			for i2,v2 in pairs(checkchar) do
				if v2.Name == v.Name then
					check = false
				end
			end
		
			local charpart = touched.Parent:findFirstChild(string.sub(v.Name,7,16))
			
			if (#checkparts > 1 and check == true and charpart ~= nil) then
				local bin = Instance.new("Model")
				bin.Name = v.Name
				bin.Parent = touched.Parent
				
				local bodyclone = v:Clone()
				bodyclone:SetPrimaryPartCFrame(CFrame.new())
				
				local parts = bodyclone:GetChildren()
				
				for i2,v2 in pairs(parts) do
					if v2 ~= bodyclone.PrimaryPart then
						v2.Anchored = false
						v2.Parent = bin
						local weld = Instance.new("ManualWeld")
						weld.Parent = v2
						weld.C0 = v2.CFrame
						weld.Part0 = charpart
						weld.C1 = CFrame.new()
						weld.Part1 = v2
					end
				end
				
				bodyclone:Destroy()
			end
		end
		
		wait(0.5)
		
		debounce = true
	end
end)

I can't understand why this won't work, the output in the console is nothing. Help!

Your if statement parenting most of your code will never be fired:

if player and debounce == true then

Because it is waiting for "player" to exist.

On line 16, you have this:

local player = game.Players:GetPlayerFromCharacter(script.Parent)

"Players:GetPlayerFromCharacter()" requires you give it the actual character's model. Which would be "game.workspace.[PLAYERNAME]". If it does not receive a players "character", it will return nil.

When player equals nil, your if statement will not pass.
