[SCRIPT] Musik won't play [Solved]

[ethics]

After picking up a note and reading it, I wanted that music starts playing.
My script for this:

void OnStart()
{
SetEntityPlayerInteractCallback("notiz", "playdatshiat", true);
}

void playdatshiat(string &in item)
{
PlayMusic("", "attic_ambience.snt", "Player", 0, false);
}


I tried everything.
Please help!
