What is the next step after I add the payment to the form?

I am making the forms just fine, but I am having a hard time knowing what to do after I integrate the payment.

Do I add a calculation field after that?  And if so, how do I know what to do?

I always get stuck in the same part, can you please help me.

The form I need help with is: https://www.jotform.com/build/90836301931151

I don't know what to add to the calculation field is there a list I can look or something that explains to me different options?

I really need some help.  I did everything above, but I use SQUARE.  I don't which products to make since I thought. that is why I had done the calculation field, why do we need products?

Also, I am trying to go to another form to see how they setup the products but I can't get to that part so I can't even copy them.

Can you just please fix this form so I can do the next form?  I don't know how to test it either.

I think I did it!!!!

Can you please triple check I did?

I checked your form and it looks good, the prices are properly passing to payment field.

If you need any further assistance, please let us know.

Thank you!
