Help! drop down menu problem (link to url)

Hi, can anyone help me please.

I need to make a pull down menu/s, that looks good.

I have tried using the invisible button technique with buttons in a mc. and the rewind command, shown here…

//
stop();
this.onEnterFrame = function() {
if (rewind == true) {
prevFrame();
}
};
this.onRollOver = function() {
rewind = false;
play();
};
this.onRollOut = function() {
rewind = true;
};

But when i add animated drop down buttons within this movie clip they are not clickable/live when you test movie ,as the movie clip covers them up.

any ideas?

This would look really good if i could make the buttons clickable/live and just linked to a url.
