Hi.  Today I was asked to create a lead form that would connect to the lead object.  The form itself was easy to set up, and it works fine.  However, now I want to add validation to the form. 

I have created a basic validation rule for the first name that looked like this:

ISBLANK( FirstName), specified the  error position to be Field, activated the validation rule.

At this point I expected for it to kick in if I were to submit a form with empty last name.  However, I got redirected to the success page, but the empty lead didn't get registered in the system.  Does it mean the validation worked?  Or was it some kind of default validation? Are there any mistakes in my workflow?

Any ideas would be very welcome.

Thanks!
