Amnesia Sound Trigger Script Help

[NuggetBlubber]

Ok so im brand new to amnesias custom story creator and so far I have made the first part of my map. What I want to do is create an area so when the player walks through it a sound will play. So far I havent been able to figure it out. This is the script code I have been using

PlaySoundAtEntity("", "enabled.snt", "guardian_area1", 6.0f, false);

and I put this script in the void OnEnter() section. I cant get it to play when I walk through the area I set it to activate on, but it will just randomly go off while im playing. Please help I am not all good when it comes to scripting thanks.
