Wp Wordpress

I have a flash animation that is 180 frames long,

frame 1-90 is a still animation
frame 91-180 is the other frame animation

I have in frame 1-90 converted that to a button symbol so I have made another layer for actions

in frame 1 of actions here is the action script

myButton1.onRelease=function(){
getURL("http://www.google.com","_blank");
}

however when I test the url is never loaded why is that?? can anyone please help
