Confused with Actionscript

[Diggers23]

Hello,

I have the following script on two different buttons

onClipEvent (load) {
num = 1;
}
onClipEvent (mouseUp) {
getURL("http://www.siesta.cat");
}

onClipEvent (load) {
num = 2;
}
onClipEvent (mouseUp) {
getURL("http://www.ipic.cat");
}

What is supposed to happen is when you roll the mouse over the first icon it shakes and then when you click it open the html page. the same with the second icon. The problem is that they are connected and when I click on one icon both pages open.

You can take a look at the fla file here.

Is my only choice to have the movie play and no link, or just the link and no movie?

Thanks
