Need some help with this script....

[Linus Ågren]

This Line: PlaySoundAtEntity(''MonsterDoor'', ''react_scare6.ogg'', ''Player'', 0.0f, true);
And this line: ShowEnemyPlayerPosition(''ScaryDude'');

I think the problem is that you use TWO ' instead of an actual ". Change the ' ' to " like this:
PlaySoundAtEntity("MonsterDoor", "react_scare6.ogg", "Player", 0.0f, true);
ShowEnemyPlayerPosition("ScaryDude");
