** SOLVED ** No sound when unlocking door?

[OriginalUsername]

the playsoundatentity is wrong, it should be more like this:

PlaySoundAtEntity("", "unlock_door", "Doorname", 0, true);

The number is the time the sound takes to fade. The file isn't even 150 seconds long, so that's a problem.
The boolean is whether the sound should remember itself when it's looping and you're leaving/entering. It also won't attach to an entity when false. (I believe)
