Not able to retrieve selected value from select dropdown on JQuery UI Modal Dialog in Firefox

Not able to retrieve selected value from select dropdown on JQuery UI Modal Dialog in Firefox

Hi,
 
I am not able to retrieve the correct selected value from a select dropdown on  a JQuery UI Modal Dialog in Firefox. This is working fine in IE(6). When I debug the value returned, its incorrect and not the value selected in the dropdown on the Modal Dialog. This is an urgent issue for me to get it resolved as the application that I am working needs to run on IE and Firefox. Any help is greatly appreciated...Thanks.
