Complex Button RollOver/RollOut Effects goto function query

Hi, I’m having a bit of a problem applying a funtion to my rollover/roll out effets button and would be very grateful if any one could help me!

I can get my anmation working perfectly but instead of the button going to a website on press:

this.onRelease = function(){

I would like to go to another frame in my movie instead i cant seem to get it to work. Can any body help? :huh:
