google calendar not displaying in FireFox with SpryTabbed Panels by Adobe

Hi, I am working on this site:http://www.entaacare.com and if you click on the allergy tab there's a google calendar displaying. Clicking on the tabs works to display each calendar in IE, but does not work in FireFox. Only the initial calendar displays. Anyone have any idea how to fix that?

Thanks!

 

use firebug to debug

 

any other ideas because Firebug isn't providing me with any information that is helpful to fix it??

 

Not sure, but it works fine in IE6, in case you were wondering

 

thanks and yes I know it works in IE...but my client obviously wants it to work in Firefox too someone in google groups thought that some call is missing....
