There are two ways on how to add your form to a Facebook page. Here are the guides:
Method 1: Using the Static HTML: iFrame tabs app. You need to use iFrame embed code, currently, I believe you are using the default script code. Here's the guide: http://www.jotform.com/help/82-Adding-Form-to-Facebook-Custom-iFrame-App-.
Method 2: Using the Add JotForm Tab app found under "Embed Form" options, here's the guide: http://www.jotform.com/help/22-Adding-Form-to-Facebook-Pages.
Let us know if that works.
