Are you getting any errors in your console?

 

Pls check whether here have reduplicate id or your define and your call is same!

 

I also get the same thing.
In my case it give this Error message
"ErrorType : document.getElementById("catid") has no properties"

Plz giv me a help
Thx

 

Make sure this javascript is running AFTER the html has generated the objects on your page. This will make the object have no properties!

 

It means the JS can not find the object with "catid" ID.

 

Ya
I resolve the prb.
I hvnt given the object ID (ID = "catid")

thx to all
