i guess it's working fine..

i think you need to check one more time..

try this code...

Hey,

The reason that you are getting that error is that the getElementById is not finding the control that you are asking for.

Can you verify that the control is rendered to the client, with that Id. i.e. right click on the page, and View Source.
