Enable debugging in your web.config file (Debug="True") and turn RemoteErrors="On". This will provide a much more detailed error message so that you can find what is throwing the NullReferenceException. Once solved, remember to reset these configurations.

That will give him the line number, but he's still going to have to learn to read a stack trace. He doesn't even seem to know it's his own Page_Load method that caused the problem. – John Saunders Jul 14 '09 at 12:08

Check the code inside your Page_Load method, its throwing a null refernce exception
