I have a different form builder (sorry cc- I bought before I found you).

My Question:

I would like to embed this "other" form into my -view cart page. Can I do this using an iframe?

Thanks.

I feel really silly right about now

Yes, this can be done. At the top of the area where you can type information on the "view cart" page, there is a row of functions that can be applied to text. Insert HTML is one of them!
