HPS script issue [SOLVED]

[Andross]

AddUseItemCallback("", "key_torture_chamber_1", "prison_1", "KeyOnDoor", true);
}

This call needs to be inside a function; propably OnStart().
Also, the closing brace in the following line must go.

void KeyOnDoor(string &in asItem, string &in asEntity)
...
void KeyOnDoor(string &in asItem, string &in asEntity)

You can't have two functions with the same name and the same parameters.

Btw.: If you set up a dev environment, the game will actually give you a rather helpful error message instead of just crashing.
