Flash Header not working properly help needed asap

I have been struggling with this for a several hours now. My header has this actionscript for the button.

 
on (release) {
     getURL("gallery.html", "bottom");
}

I named the bottom frame bottom of course. It isn’t opening in the bottom frame but it is opening up an entirely new window. Do I point it to the page that contains the frameset?
