..."instance is not a valid member of"...?

i'm creating a paper morph GUI with a remote function that will send the name of the button clicked to the server, and it will use that information to clone the correct morph and weld to the player. i'm pretty new at scripting and this is the most advanced thing i've taken on so far, so its probably messy i know.

localscript:

script.Parent.MouseButton1Click:connect(function()
	
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local morph = ReplicatedStorage:WaitForChild("Morph")

local img = script.Parent.Name

morph:InvokeServer(img)
print("decal id: ",img)

end)

server script:

ReplicatedStorage = game:GetService("ReplicatedStorage")

function morphPlayer(player,img)
		print("decal id recieved: "..img)
	
	if player.Character:findFirstChild("Humanoid") ~= nil then
		
		--===
		local morph = game.ServerStorage.Morphs.img
		--===
		
		local chest = game.ServerStorage.Morphs.morphvalue.Chest:clone()
		chest.Parent = player.Character
		
		local a = player.Character:GetChildren() 
		for i=1, #a do 
			if (a[i].className == "Part") then 
				a[i].Transparency = 1 
		local b = player.Character:GetChildren() 
		for i=1, #b do 
			if (b[i].className == "Accessory") then 
				b[i]:remove()
			end
		
		local children = chest:GetChildren()
		for i=1, #children do
			if children[i].className == "Part" then
				local W 	= Instance.new("Weld")
				W.Part0 	= chest.Middle
				W.Part1 	= children[i]
				local CJ 	= CFrame.new(chest.Middle.Position)
				local C0 	= chest.Middle.CFrame:inverse()*CJ
				local C1 	= children[i].CFrame:inverse()*CJ
				W.C0 = C0
				W.C1 = C1
				W.Parent = chest.Middle
			end
				local Y 	= Instance.new("Weld")
				Y.Part0 	= player.Character.Torso
				Y.Part1 	= chest.Middle
				Y.C0 		= CFrame.new(0, 0, 0)
				Y.Parent 	= Y.Part0
		end

		local child = chest:GetChildren()
		for i = 1, # child do
			if 	child[i].className 	== "Part" then
				child[i].Anchored 	= false
				child[i].CanCollide = false
						end
					end
				end
			end
		end
	end
end
ReplicatedStorage.Morph.OnServerInvoke = morphPlayer

THE ERRORS ARE: img is not a valid member of Folder - localscript line 8

img is not a valid member of Folder - serverscript line 9

when it prints in the output, the name is correct, so I don't know what to do here

make sure all names match including caps local script

script.Parent.MouseButton1Click:connect(function()
	 
	local ReplicatedStorage = game:GetService("ReplicatedStorage")
	local morph = ReplicatedStorage:WaitForChild("Morph")
	 
	local img = script.Parent   ---i moved the last part Name 
	 
	morph:InvokeServer(img.Name)
	print("decal id: "..img.Name)
 
	end)

if it does not work tell me and i will fix my answer
