Called on client not server!? [STILL UNANSWERED]

local Text = script.Parent.Parent.TextBox.Text
		if Text ~= "Type here"
			then
			local Text2 = Text.."k"
			local FilteredT = game.Workspace.RemoteFunctions.FilterName:InvokeServer(Text2)
			local StringLength = string.len(FilteredT)			
			local FilteredText = string.sub(FilteredT, 1, StringLength-1)
			if string.find(FilteredText,"#",1,false) ~= nil then
				script.Parent.Text = "Type here"
			else
				script.Parent.Parent.Visible = false
				end
		end

^ Local script on the client

script.Parent.OnServerInvoke = function(Player,Text)
	return game:GetService("Chat"):FilterStringForBroadcast(Text, Player)
end

^On the server

Any ideas why it is telling me that I am using Chat:FilterStringForBroadcast on the client when I am clearly using it on the server?? Thanks!

It's probably being awfully pedantic. Try:

script.Parent.OnServerInvoke = function(Player,Text)
   local x = game:GetService("Chat"):FilterStringForBroadcast(Text, Player)
	return x
end

Otherwise, you might need to extend the contents of the OnServerInvoke function into functions within the client-sided script, ROBLOX really is being over the top (it's not your fault)!.
