Unique database field inserted, but page is blank
I'm trying to add validation that searches whether a e-mail already exists when user is registering. When adding added code similar to the wizard's output, I end up with a blank page. I stripped down the server validations behaviour to only include the unique db field validation. I read that the Key value should be 0 from another post, but the SA wizard adds session variable values. Attached screenshot of wizard and page.
