R – clickTAG isn’t working

I made a banner ad and the site gave me this code to work with:

on (release) {
if (clickTAG.substr(0,5) == "http:" ) {

getURL(clickTAG, "_blank");
}
}

I made an invisible layer and put this code on it. The swf showed the hand, but when I clicked on the banner nothing happened, on my end or on the live site.

Then I used this code:

on(release)
{getURL(clickTag,"_blank")}

On my end it would open a blank page. On their end they got a 404 message.

Why is it not connecting to the server and opening the link? Is there something in my file that could be preventing either clickTAG from working?

I exported in Flash 9. I'm using a loop code. I have many layers and masks, but all are under the invis. layer.
