Add an input field from an external source

Hello, I created a form here on JotForm and downloaded the code for Dreamweaver.

What I need to do is integrate jotForm code with a 3rd party code. (few checkboxes in a table).

I can easily prepare the code in Dreamweaver, but when a user submit the form, how can I check the result of the submission here in JotForm?

I am a bit confused about this point. Is there a way to display the custom code result?

By clicking the URL above you can see...the first part is Jotform and the green table is an external code. 

Thank you in advance.
