Can someone help me know why this isn’t working?

I have a loader (aka controller) that loads my main collection when the user selects the play button. I’m Trying to also send a message to the main telling the main collection what mode to play. I guess I can create 3 different collection of game modes, but it’s so much smaller code if I just capture the few minor differences in the main collection. So anyway I get this error:

Could not send message ‘casual\_game’ from ‘loader:/go#loader’ to ‘main:/factories#startgame’.

I’ve done a print(msg.url()) and confirmed it’s the correct full URL from the loader to the startgame script.

this is my loader script:

```lua
local function load_menu(self)
	msg.post("go#mainmenu", "load")
	msg.post("go#mainmenu", "enable")
end

local function unload_menu(self)
	msg.post("go#mainmenu","unload")
end

local function load_main(self)
	msg.post("go#main", "load")
	msg.post("go#main", "enable")
	msg.post("main:/factories#startgame", hash("casual_game"))
end

local function unload_main(self)
	msg.post("go#main", "unload")
end

function init(self)
	msg.post(".", "acquire_input_focus")
	load_menu(self)
end

function on_message(self, message_id, message, sender)
	if message_id == hash("start_casual") then
		unload_menu(self)
		load_main(self)
	elseif message_id == hash("goto_menu") then
		unload_main(self)
		load_menu(self)
	end
end

```

Any suggestions are very much welcomed.

Already solved it. I had to wait for the proxy to load the collection.

```lua
if message_id == hash("proxy_loaded") then
		if game_mode == "casual" then
			msg.post("main:/factories#startgame", hash("casual_game"))
		end
	end

```

Thank you.

Usually the [Question category](https://forum.defold.com/c/questions/5) is the best, unless you know for sure that it is a bug in which case the [Bugs category](https://forum.defold.com/c/bugs/6) is best.
