Fix Broken Wordpress Plugin

I am using this plugin... [login to view URL] However, the redirect is not working after a successful submission. Watch the video explanation here... [login to view URL] I have attached my edited plugin code to this job. I would prefer someone to troubleshoot on their own without requiring login to my wordpress. I can upload the test files with your edits. As you can see in the video, for some reason the output is not being displayed after a successful submission. I will also provide you in a private message the page where the script is currently installed. Thanks!
