What I need to know is how to all a customer to make a donation for an amount of their choosing? I cannot figure out hoiw to open the $amt field for the cust to enter any amount.

Hello Matt,

Thanks for reaching out to Jotform Support. It's not possible to collect a donation when using the regular product field, In order to calculate the product amount total and any donation field, we need to use regular field for the product and pass the total amount to your preferred payment integration. Let me show you how:

1. Create your products using single/multiple choice field, and then add the prices using the Assign Calculation Value.
2. Add a number field for the donation field and add a Form Calculation Widget to your Form, set it as hidden, then create the necessary calculation for the total
3. Add your payment integration (in my demo form it would be Square) then click on the Wand icon.

• Under the Payment Type, select User Defined Amount.
• Under Get Prices Form, select the Form Calculation Field.

You can check my demo form here. To inspect the form builder, you may clone this form to your account by following this guide.

Give it a try and let us know if you need any additional help.
