It doesn't work, maybe impossible?!

Firstly
You didn't tell the script where its going to play this sound, You also need to type in the entity the sound will come fro.
Otherwise you can use PlayGuiSound

PHP Code: (Select All)

PlayGuiSound("quest_completed", 1.6f); 


Secondly, try using other shelf entities, not movable ones.
Maybe the ones from the storage file and make sure they are the correct name.
