RemoteFunction not returning errors help?

So I'm trying to send a name to a reciving script and then that script will find the player in the workspace, check if a part that is in the list is in the player, then clone it and put it in workspace.

The only reason I'm doing this is because of filtering enabled

The sending script: (Local)

local Player = game.Players.LocalPlayer

Mouse.Button1Down:connect(function()
	local name = Player.Name
	game.Workspace.BlockInserter.BlockInsertation:Invoke(name)
end)

The receiving script: (Normal)

NormalParts = {"Slab","Wall","Plate"}

script.BlockInsertation.OnInvoke = function(name)	
local chil = game.Workspace[name]:GetChildren()
	for i, v in pairs (NormalParts) do
		if chil.Name == v then
			local clone = name[v]:Clone()
			clone.Parent = game.Workspace
		else
--			game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay.Description.Text = "Undefined part value: "..i.."
--			game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(0.8, 0,0.9, 0),"InOut","Elastic",2.6,false)
--			wait(15)
--			game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(-1, 0,0.9, 0),"InOut","Elastic",2.6,false)
		end
	end
end

#Before I start, There is something I need to say, I do not know what you mean by "returning errors".

I think you should've just used a remote event instead of a remote function. If you want a way to find if the script errors then use pcall. Anyway, I see the errors in the Normal script.

#Error

local chil = game.Workspace[name]:GetChildren() --Part of code
    for i, v in pairs (NormalParts) do
        if chil.Name == v then --Chil is an array, not a single object. It's like saying: "Banana tastes sweet, blue, 231, and it also tastes purple."
            local clone = name[v]:Clone()
            clone.Parent = game.Workspace

You also need to include the player object into the script.

#Final Product What I think you should do is use a remote event instead. Since there is no reason to add a remote function but to make the script longer. ##Local Script

local Player = game.Players.LocalPlayer

Mouse.Button1Down:connect(function()
    local name = Player.Name
    game.Workspace.BlockInserter.BlockInsertation:FireServer(name)
end)

##Regular Script

NormalParts = {["Slab"] = true,["Wall"] = true,["Plate"] = true}

script.BlockInsertation.OnServerEvent:connect(function(game:GetService("Players"):WaitForChild([PLAYER_NAME NEEDED HERE]),name)   
local chil = game.Workspace[name]:GetChildren()
    for i, v in pairs (chil) do
        if NormalParts[v.Name] then
            local clone = workspace:FindFirstChild(name).Slab:Clone() or workspace:FindFirstChild(name).Wall:Clone() or workspace:FindFirstChild(name).Plate:Clone()
            clone.Parent = game.Workspace
        else
--          game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay.Description.Text = "Undefined part value: "..i.."
--          game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(0.8, 0,0.9, 0),"InOut","Elastic",2.6,false)
--          wait(15)
--          game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(-1, 0,0.9, 0),"InOut","Elastic",2.6,false)
        end
    end
end)

Hope it helps!

NormalParts = {"Slab","Wall","Plate"}

script.BlockInsertation.OnInvoke = function(name)   
local chil = game.Workspace[name]:GetChildren()
    for i, v in pairs (NormalParts) do
        if chil.Name == v then
            local clone = name[v]:Clone()
            clone.Parent = game.Workspace
        else
 game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay.Description.Text = "Undefined part value: "..i.."
 game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(0.8, 0,0.9, 0),"InOut","Elastic",2.6,false)
wait(15)
 game.Players.player.PlayerGui.MoneyDisplay.ErrorDisplay:TweenPosition(UDim2.new(-1, 0,0.9, 0),"InOut","Elastic",2.6,false)
        end
    end
end

Try removing the "--'s," that makes the line a comment. This isn't really an answer, just a recommendation.
