Dynamic dropdown problem in firefox.
 

Hi,
I am populating 2 dropdowns in a webpage. the second dropdown is being populated on the basis of the category selected in first dropdown. I am doing it through AJAX/ASP.

The code is working fine in Internet explorer but when I open the page in firefox then after selecting an option from first dropdown, one more dropdown appears with the second dropdown.

Somebody please suggest me how can I sort out this problem?

Thanx in advance
