Popup does not appear after clicking on link

Hi,

I tried to use this plugin on two different WP pages (on my localhost) but I could not make it work. Firebug showed two error messages as shown below:

missing } after property list
$('a.wikipopLink').fancyZoom({scale...wp-content/plugins/wikipop/images'});

and

setFrameSrc is not defined
onclick()
event=click clientX=320, clientY=346
setFrameSrc("John Ratzenberger", "");

I tried jQuery 1.4.4 and 1.5.2, no change. When clicking on the link of the key word, nothing happens. I used different browsers, still nothing changed.

Any idea how to make that work?

Thanks, best regards,
Steffen
