My buttons just stopped working!

hey guys!

im 95% thru my boss’ website and all my buttons have just stopped working…
theyre movie clips btw and not ‘buttons’

They were working fine when i added in a new “intro” scene to the movie. But as soon as i added a third “preloader” scene to my movie my buttons stopped working…ill post the movie if needed but if anyone has any quick fixes or ideas they would be much appreciated.

heres my button code:

on (release) {
getURL(“”, _blank);
on (press) {
on (rollOver) {
on (rollOut) {
