When do you get the Sys.ArgumentNullException error? Also, try getting rid of the Style="display: none" on the Panel...

I get the error when the page loads.
I Got rid of the Style "display : none" and I get the same error on page load.

Thanks Damien. The asp buttons weren't plugged into anything I am guessing. My new challenge with this now is to have the email send, and display a message that the send was a success before leaving modal state.
At least this one issue is handled.
