Collapse area not working?

[KeysOfMyMind]

it might be because you are setting the area to be inactive, and it dosen't get active anytime later in your script

void Push(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("Door_Slam", "react_pant.snt", "Push", 0, false);
SetEntityActive("collapsearea", false);
AddPlayerBodyForce(-8000000, 0, 0, false);
}

Thanks works now, how do I use the PlayMusic function?
I can't understand the syntax it's latin to me.
Help please ^^
