Problem With Form After Putting In Captcha Code

I'm having a problem with my form code after I put the captcha code in. The Captcha code is working fine, but I cannot get it to pull up the correct page when the form is submitted correctly. Instead it just goes to a blank page - the form gets sent and comes through the email, but it doesn't notify anyone of that, so they have no way of knowing if it worked or not. You can view it here: http://bit.ly/1rSWnJ4. I've attached the two form files I'm having trouble with. Any advice is much appreciated!
