Make a pop up box when someone clicks summit button

Hi. I am wanting to make a box that pops up with a disclaimer when someone clicks on the submit button on my form. They can then, read the disclaimer, and then go ahead and submit the form if they agree. I have create a form and embedded it as a pop up box, which works great, but if I put it over the "submit" button, when they close it, they still can't get to the submit button. It just keeps opening up that pop up box.

We do not have that functionality in our tool, but we have widgets form terms you can use: https://widgets.jotform.com/widget/short_scrollable_terms
