Fatal Error... again... >.> [SOLVED]

[Karai16]

This is the error I get once I start up my map. it has to do with this piece of code.

Code: (Select All)

void OnStart()
{
    SetPlayerInteractCallback("RoomDoor", "showdoortext1", true);
}

void showdoortext1(string &in asParent , string &in asChild)
{
SetMessage("Message", "doortext1", 0);
}

I'm probably not stringing things in right, but could anybody tell me what's wrong?
In case you don't know what I'm trying to do, I'm trying to make text appear on the screen saying the door's locked
