Thank you page is cut off on website

I have my form set up to where it has the thank you pop-up/page display after a client has filled out the form. Once the thank you page comes up after the form is complete it's almost cut in half, it does the same thing no matter what page I choose to use as a thank you page. I use Weebly. I'm wondering if this is a setting I'm unaware of on my actual site or if there's a setting in jot form I can tweak. 

Screenshot is attached. Thank you!

I suggest you try using the iFrame embed code to embed the form to your website. Here's how: Getting the Form iFrame Code. That should fix the issue with the Thank You page. 

Hello, 

Please try the new JotForm App for Weebly which helps you add and create forms directly from Weebly. 

See https://www.jotform.com/blog/198-Add-JotForm-to-your-Weebly-Site-with-Ease

It would be great if you could tell us what you think of the App. 

Feel free to comment on the blog post above; we value your feedback.
