Gravity Forms + prettyPhoto

I am trying to set up a gravity forms SIGN-UP form using prettyPhoto. This form will just require the user to insert a phone number and their name.

I was able to get the form on the prettyPhoto using hidden inline content, the problem that I am having is that there is validation/notification messages when clicking submit. For example when the form has not been filled out and I click submit, the prettyPhoto closes and so there is no sign of error messages. The same issue occurs if i fill the form correctly, and submit it, there is no messages, so users won't know if there info was submitted, the prettyPhoto just closes.

Can anyone please help?

Thank you in advance. I am loving Gravity Forms. :)

Unfortunately, I am working locally. I was not using AJAX on the form, after seeing your message, I enabled it, and now the prettyPhoto does not close neither when submitting blank nor when filled out. I still do not see messages though, I would like to see messages. Is there anyway to do this?

Thank you very much for such great fast support. I was not expecting such a fast response, I appreciate it.

Thank for your help, I will try to put the site online for you to check it out, maybe you can figure it out.

Thanks gain. I will let you know as soon as i put it online.
