I followed your tutorial to use the modal box to display a form. I used a simple form first which would not submit. I then tried to use conditional logic and this also will not work for me. I added the enqueue functions to my functions.php and I have called the form using php in the plain page template. I think I may have entered the enqueue function wrongly :(
Please let me know what you think I should do. Here is a link to the site, please ignore the absolute mess it is undergoing a lot of changes http://www.docsense.net/ click the let's get started button to open the modal window. Thanks!
