Why does the submission my pop-up form mess-up my other form?

When someone submits my JotForm pop-up form, my other JotForm gets messed-up.
See screenshot here (green arrow points to form issue).

I have also provided the URL so you can see what I'm referring to (after you submit pop-up form).

How do I change code to allow the two forms to play well together?

Thanks in advance for any help.

Please try embedding the other form(not the popup one) with the Iframe code instead: http://www.jotform.com/help/148-Getting-the-Form-iFrame-Code 

Before you embed the code, paste it in a text editor like WordPad, you will notice two part of codes, only copy and embed the Iframe part in your webpage, example:

It appears to have worked. Thank you, BDAVID!
