Contact form confirmation in Fancybox popup?

[PicnicTutorials]

Good morning,

 

Contact form confirmation in Fancybox popup? I'm using Fancybox to display a simple contact form. The form is inline (within the main page) in a hidden div. All I need is to validate the simple captcha (2 + 2 = ?), and to display a thank you message once submitted. That I can do, however, I need this to all take place within the fancybox popup. That I can't do! Then the user simply closes the popup once finished as normal. Anyone dealt with this before? Thanks!

 

This post got me sort of close http://www.webmaster-talk.com/php-forum/154171-contact-form-popup-confirmation.html but the on pressing the submit button it closes the fancybox window. But when I reopen the fancybox popup window the thank you message is there. But, I also cant get the message to leave either without closing the window and refreshing the page (FX wants to "resend the page").

Two things I'm tooling around with. "inline form validation" and/or hidding the form after submit is pressed to reveal a thank you message behind it. I haven't made any progress yet, still just googling. Just thought if you all had done this before...
