How to add payment options to my form?

Have a form with Paypal payment at the end.  I have a customer that wants to pay with a check and because I didn't set that up yet, they can't submit the form.  Can someone walk me through that?

You need to use hide/show conditional logic for that. However, the items in your Payment field will be listed in the multiple-choice element. Once done, you can assign calculation values to each option.

Then use the form calculation widget to get the value of the chosen option.

Once you set up the form calculation widget, add a single option element and then show/hide the PayPal field based on the user's answer.

You can then setup PayPal checkout to get the value of your items in the form calculation widget.
