Movie wont load url!

Hi

Im hoping someone on here can help me.

Im creating a banner for a website using the complex rollout effects tutorial on this site.

http://www.kirupa.com/developer/mx2004/button_effect.htm

However what i would like to do is place two buttons inside the button effect - this will effectively allow two html links open up - to make a menu.

I am currently using the following script on the buttons:

on(release){
    getURL("residential_developments.html");
}

however this doesnt appear to work!!
Can anyone offer me some guidance!
