Thanks for getting back to me. To provide you with more information. Each UE is triggered by the associated submit button for that form. So the Contact is triggered by the contact button, the Appointment form is triggered by the appointment button and so on...
I still think that even though I have three separate captcha instances, somehow the session is returning invalid true because the captcha is validating to the wrong session.
Digging into it a bit further when I go to the Server Behaviors panel and check the "validation show if" for the captcha, it is set to Validations Fail on any and then an associated like entry for the Captcha session.
So that is looking correct to me... Any ideas why the Appointment and the Job App form are returning invalid true?
