Hi guys,  
I’m trying to get the form validator to work - and it almost does. What  
happens, I believe, is that it throws the error properly, but it never  
makes it back to the page to post the error. Instead, it kind of blows  
up.

I used the same basic code the scaffold uses, so I’m not sure why it’s  
not working. If you guys wouldn’t mind… controller = Signups, model =  
Customer

Cheers. And thanks in advance!
