Please help with onSoundComplete

hello

I have a presentation which issplt into several different movies which are linked together by buttons, all im trying to do is add a sound which will play when the user moves over the button, and then another that will play when they click on the button; i got this to work once but it cut off the sound because it loaded a new movie, so i found the onSoundComplete command, which i’ve tried in a load of different ways but nothing works…
here’s the code i’ve got at the moment:

on (rollOver)
{
mySound = new Sound(this);
mySound.attachSound(“twisted1”);
mySound.start(0, 0);
}
on (release)
{
mySound = new Sound(this);
mySound.attachSound(“twisted2”);
mySound.start(0, 0);
twisted2.onSoundComplete = function(loadMovie(“history.swf”, “this”));
}

and this is the error that im getting:

Error Scene=home, layer=links, frame=1:Line 12: ‘)’ or ‘,’ expected
twisted2.onSoundComplete = function(loadMovie(“history.swf”, “this”));

I’ve tried a few things but i just seem to get more errors…
I need to try and sort this by tomorrow (though I’ll still want to know how to do this after tomorrow) so if anybody knows what I’m donig wrong then please please help me out.

thankyou
Tom
