im kinda working on the same problem.. i have links in my footer to other "off site" pages that i want to work as a popups...

this one works, because i got the code from the website...
Code:
<li><a href="javascript:void(0);" onclick="window.open('http://www.justhost.com/ecertified?domain='+document.domain+'','JustHost',
'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,
resizable=0,width=570,height=680,left=300,top=200');"><img style="border:0px;" src="http://www.justhost.com/img/
greenbadges/badge4.gif" alt="Green Web Hosting" /></a></li>
however, when i try to duplicate it for the other links in the footer, using the same "formula" it doesnt work.

also, it is my understanding that using a href="javascript:void(0);" is functional, but not really the best way to do it, so i would be happy to re-work this code if someone can lend a hand!

site is here:

and i am working on the footer (links to humane society, my page is green, facebook, firefox)
