Hi KristinWard. Welcome to the forums.
Just put some random numbers in the contact box.
It's not really clear what you mean by that. Anyhow, the Get a Quote button popup seems to work fine on desktop. Does it replicate on desktop for you if you make the browser window smaller? If so, what size? Or if not, what size is the window of the laptop, and what browser are you seeing this in?
The form has a set width of 1020px which might be the problem. That's way wider than the box itself, which is set to 80% of that 1020px. Do you want the box to be 10% of the browser width? Then try removing that width on the form, and maybe using this instead:
and then remove the width setting on the table itself.
