I checked the page you included on your post http://glidewelldental.com/promotions/glidewell-now-office-solution/ along with the stand alone version of your form https://form.jotform.com/70407103210133 and here's how they looked liked from my perspective:
It's jumping up and down on your website with horizontal and vertical scrollbars. I'm seeing you're using WP and you embedded the form using the script. Can you try re-embedding it using the iFrame Embed codes instead and see if that would make a difference?
1. First, try with the default iFrame codes

(only do the next step if this one fails)
2. If the issue persists, even with the iframe codes, remove the <script></script> part then try again.
