Button not working in flash player 8?

programming flash
1

Hi, can anyone help with this script?

The buttons work in flash player6, i have now changed the setting to publish in flash player 8 as i have added some filters, but now the buttons do not work!

The buttons are really movieclips with code!

Can i modify the code?

Here is the code within the button MC:

//
stop();
this.onEnterFrame = function() {
if (rewind == true) {
prevFrame();
}
};
this.onRollOver = function() {
rewind = false;
play();
};
this.onRollOut = function() {
rewind = true;
};
this.onRelease = function() {
_root.gotoandStop(“home”);

};

Cheers!
