How make this script? (SOLVED)

[Abihishi]

I have:
void OnStart()
{
AddUseItemCallback("", "key1", "door1", "UseKeyOnDoor", true);
AddEntityCollideCallback("Player", "ScriptArea", "Scrypt1", true, 1);
}

void Scrypt1(string &in asParent, string &in asChild, int alState)
{
SetMessage("MessageCategory", "MessageEntry", 0);
}

But this not work in game.
