The form will not submit when filled

Hello, I am having trouble with my form being able to submit. It submit just fine when none of the fields are filled in but, if you fill in the fields to order a product and then hit submit it gets stuck on "please wait" and then it never processes through! Hope you can help so I can help an organization to raise some money! Thank you so much for your time.

You have Square in the form, but it is not yet connected to any Square account. That is the reason why the form won't submit. Please edit the form, and finish your integration settings with Square.
