3)the total payment due in my calculation won't populate to the "Pay with Square" field.

To pass a total to a payment field, please follow this guide: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field 

Thank you!
My "Get Price From" options are:
None (Manual)
Total Payment Due
No Calculation option exists...?
...

You need to add form calculation so you can pass the total amount to your payment integration. If your total value is textbox then replace it with the form calculation widget.

It is set up as a widget already....?
...

Form calculation is a widget that can do a calculation. Since you have a total price and it is a number/text field. Payment integration can't detect that field, you can use the form calculation instead to pass the total value to your payment integration. If you do not want to change your condition then just change the output where the total goes.

I'm sorry, I do not understand this at all...?
...

You need to simply select the field where the total is obtained, so if the total to be paid is displayed in the "Total Payment Due", that's the field you need to select for the "Get Price From" option.

OK, I've done that & it still is not working. Is there any way you would*
just fix it*? I've been working on this form for weeks and I'm sick to
death of it. I really need to post it & get it going because it's holding
up everything else.
Hoping so!
Tnx much

You need to click on the Save button after you select "Total Payment Due":

Otherwise, the selection won't save.

Also, you must connect with your Square account and put your integration in LIVE mode:

So, after you connect with Square, put the integration in Live mode, and select the "Total Payment Due" in the "Get Price From", please make sure to click on the Save button.

Done.....but still not working,,,?
...

I checked your form again: https://form.jotform.com/90356463329158 

And it is not connected to your Square account, still in test mode, and the integration is not getting the price from "Total Payment Due" field.

When you mean "it is not working", could you explain further?

Did the connection fail? Did you get an error message if this was the case? Or did you save, but the "Save" button did not actually save anything?

Yea!! Got it! Finally, what a relief!!
Tnx for your help!
