To my understanding, you're having issues with the form embedded in your website. I also see that you have created a new thread explaining the issue you're having. http://www.jotform.com/answers/704613-My-problem-is-the-envelope-will-not-open-all-the-way-the-message-area-will-not-allow-input-and-I-would-like-the-entire-thing-to-be-on-the-left-side-#0
You may refer to that thread and we will attend to you there.
