It is changing indeed. So I guess I will try using getElementsByClassName( 'i-can-constant')[0]
instead. Thanks.

Hi 

When you click 'View Source Code' in a browser, it shows you the html loaded 
first time the page was loaded and does not show the dom changes done using 
ajax. If you want to see the latest dom, install firebug on firefox(chrome 
has a very similar one by default) and enable it by clicking on the bug icon 
on the status bar. 


Also, how are using getting the element id of select in your javascript ? 

regards 
Taha
