Error with linking Flash buttons

hello,

i m using flash  player 8

and when im trying to make a link button of my ready  tamplate im getting an error.

i program the link action like this:

on(release) {

           getURL("http://www.carmela-gallery.net");

}

**Error**  Symbol=About us, layer=Layer 1, frame=1:Line 1: Mouse events are  permitted only for button instances
     on(release) {

Total  ActionScript Errors: 1      Reported Errors: 1

and of curse the link isnt  working when i test it. will be be happy if you help me to get forward  with this problem.

let me know how we get forward with it.

thanks,  Eden.
