Getting Square Payment Error on Test Mode

Just wanted to try this from another angle. We also use Square when we set up in remote locations to take payments. I tried the Square payment integration, which set up fine and accepted our login and password. I set up the Square in the Test mode and received the following error: 

So if there is an error in both Authorize.net and Square is there an issue with the way I'm building the forms or is this a Gateway error in JotForm?? We have been receiving complaints every day for the last week for not having our online registrations and payments on our website! We need help, please!

I could not reproduce this problem. The form submits properly when testing on test mode.

You can try my test form: https://form.jotform.me/726374585524

I suggest to please re-connect your Square payment field then use the provided test cards from Square here https://docs.connect.squareup.com/articles/using-sandbox.
