Why does my script say this? attempt to index nil with 'Name'

Hello. I hope this should be a quick fix. Here is my localscript:

local LegionFrame = script.Parent.Parent.Legions
 local UniformFrame = script.Parent.Parent.Uniforms
 local MorphsDir = game.ReplicatedStorage.Morphs
 local Libs =game.ReplicatedStorage.Libs
 local RemoteEvent = game.ReplicatedStorage.Youneedthis
 local Player = game.Players.LocalPlayer




for i,v3 in pairs(MorphsDir:GetChildren()) do
    local Button = Instance.new("TextButton")
    Button.Size = UDim2.new(1,0,0,50)
    Button.BackgroundTransparency = 1
    Button.Font = "SciFi"
    Button.TextSize = 30
    Button.TextXAlignment = "Left"
    Button.TextColor3 = Color3.fromRGB(255,255,255)
    
    Button.Text = v3.name
    Button.Parent = LegionFrame
    
    Button.MouseButton1Click:Connect(function()
         for i,v2 in pairs(UniformFrame:GetChildren()) do
         	if v2.ClassName == "TextButton" then
            	v2:Destroy()
            end
         end
		 for i,Morph in pairs(v3:GetChildren()) do 
	     	local Button2 = Instance.new("TextButton")
	        Button2.Size = UDim2.new(1,0,0,50)
	        Button2.BackgroundTransparency = 1
	        Button2.Font = "SciFi"
	        Button2.TextSize = 30
	        Button2.TextXAlignment = "Left"
	        Button2.TextColor3 = Color3.fromRGB(255,255,255)
	        
	        Button2.Text = Morph.Name
			Button2.Parent = UniformFrame
			
			Button2.MouseButton1Click:connect (function()
				print(Button2.Text)
				RemoteEvent:FireServer(Morph, Button)
			end)
		end	
	end)		
end

Here is the script:

-- This is just a part of the script the other things are unimportant.
game.ReplicatedStorage.Youneedthis.OnServerEvent:Connect(function(Player, Morph, Button)
	coroutine.resume(coroutine.create(function()
	if Player.Character:FindFirstChild(Morph.Name) == nil then
		wait(0.1)
		local FindMorph = game.ReplicatedStorage.Morphs:FindFirstChild(Morph.Name)
		local Cloned = FindMorph:FindFirstChild(Button.Name):Clone() -- Error here
		Cloned.Parent = Player.Character
		for i, v in pairs(Cloned:GetChildren()) do
			coroutine.resume(coroutine.create(function()
			if v:IsA("BasePart") then
				if v.Name ~= "Middle" then
					local w = Instance.new("Weld")
					w.Part0 = Cloned["Middle"]
					w.Part1 = v
					w.C0 = w.Part0.CFrame:inverse() * CFrame.new(w.Part1.Position)
					w.C1 = w.Part1.CFrame:inverse() * CFrame.new(w.Part1.Position)
					w.Parent = w.Part0
				else
					coroutine.resume(coroutine.create(function()
						wait(0.1)
					local w = Instance.new("Weld", Player.Character["Torso"])
					w.Part0 = Player.Character["Torso"]
					w.Part1 = v
					w.C0 = CFrame.new(0, 0, 0)
					end))
				end
			end
			end))
		end

I found a fix myself by adding:

RemoteEvent:FireServer(Morph, Button, Button2)

It says no errors, but I found out the morph script isn't working.

game.ReplicatedStorage.Youneedthis.OnServerEvent:Connect(function(Player, Morph, Button, Button2)
	coroutine.resume(coroutine.create(function()
	if Player.Character:FindFirstChild(Morph.Name) == nil then
		wait(0.1)
		local FindMorph = game.ReplicatedStorage:FindFirstChild(Button.Name)
		local Cloned = FindMorph:FindFirstChild(Button2.Name)
		local Cloned2 = Cloned:GetChildren()
		Cloned.Parent = Player.Character
		for i, v in pairs(Cloned:GetChildren()) do
			coroutine.resume(coroutine.create(function()
			if v:IsA("BasePart") then
				if v.Name ~= "Middle" then
					local w = Instance.new("Weld")
					w.Part0 = Cloned["Middle"]
					w.Part1 = v
					w.C0 = w.Part0.CFrame:inverse() * CFrame.new(w.Part1.Position)
					w.C1 = w.Part1.CFrame:inverse() * CFrame.new(w.Part1.Position)
					w.Parent = w.Part0
				else
					coroutine.resume(coroutine.create(function()
						wait(0.1)
						local w = Instance.new("Weld", Player.Character["Torso"])
						w.Part0 = Player.Character["Torso"]
						w.Part1 = v
						w.C0 = CFrame.new(0, 0, 0)
					end))
				end
			end
			end))
		end
		for i, v in pairs(Cloned:GetChildren()) do
			coroutine.resume(coroutine.create(function()
			if v:IsA("BasePart") then
				v.Anchored = false
				v.CanCollide = false
			end
			end))
		end
		if Player.Character:findFirstChild("Shirt") ~= nil then
			Player.Character["Shirt"]:remove()
		end
		if Cloned2:findFirstChild("Shirt") ~= nil then
			Cloned:FindFirstChild("Shirt"):Clone().Parent = Player.Character
		end
		if Player.Character:findFirstChild("Pants") ~= nil then
			Player.Character["Pants"]:remove()
		end
		if Cloned2:findFirstChild("Pants") ~= nil then
			Cloned:FindFirstChild("Pants"):Clone().Parent = Player.Character
		end
		for i, v in pairs(Player.Character:GetChildren()) do
			coroutine.resume(coroutine.create(function()
			if v:IsA("CharacterMesh") then
				v:remove()
			end
			if v:IsA("Accessory") then
				v:remove()
			end
			end))
		end
	end
	end))
end)

I do not understand why this is not working.

Quick fix, you need to use uppercases.

-- I declared all the locals above.
for i,v3 in pairs(MorphsDir:GetChildren()) do
    local Button = Instance.new("TextButton")
    Button.Size = UDim2.new(1,0,0,50)
    Button.BackgroundTransparency = 1
    Button.Font = "SciFi"
    Button.TextSize = 30
    Button.TextXAlignment = "Left"
    Button.TextColor3 = Color3.fromRGB(255,255,255)

    Button.Text = v3.Name --//Made it uppercase
    Button.Parent = LegionFrame

    Button.MouseButton1Click:Connect(function()
         for i,v2 in pairs(UniformFrame:GetChildren()) do
            if v2.ClassName == "TextButton" then
                v2:Destroy()
            end
         end
         for i,Morph in pairs(v3:GetChildren()) do 
            local Button2 = Instance.new("TextButton")
            Button2.Size = UDim2.new(1,0,0,50)
            Button2.BackgroundTransparency = 1
            Button2.Font = "SciFi"
            Button2.TextSize = 30
            Button2.TextXAlignment = "Left"
            Button2.TextColor3 = Color3.fromRGB(255,255,255)

            Button2.Text = Morph.Name
            Button2.Parent = UniformFrame

            Button2.MouseButton1Click:connect (function()
                print(Button2.Text)
                RemoteEvent:FireServer(Morph, Button)
            end)
        end 
    end)        
end

Another thing is:

local Cloned = FindMorph:FindFirstChild(Button.Name):Clone() --//You cannot clone a name lol
