Linking an image (movie clip) to external URL

I am the newest of flash newbies, and am learning through tutorials, so bear with me and my lack of flash vocabulary!

Trying to link an image to an external link, here is my code:

stop ();

clickThrough_mc.onRelease = function(){

getURL("http://weber.edu/careerservices/studentjobfair.html", _self);

}

Here is a screen shot:

When I test it, there is no hand icon indicating it is a link, and it is not clickable. Help?

Thanks!
