Custom error? music won't work

[Radical Batz]

I'm trying to make a soundtrack in my custom story and whenever I load it, it gets me this error message "FATAL ERROR:Could not load script ile
'custom_stories/Name/maps/Name.hps'!
main(3,7):ERRata type can't be 'void'
main (3,16):ERR:Only objects have constructors

and here is my hps file:



void OnStart()
{
void PlayMusic("06_amb.ogg", true, 0.3, 4, 1, false);
}

void OnEnter()
{

}

void OnLeave()
{

}

Do you see anything wrong because I don't
