How to integrate "other amount" in paypal payment

This is my third email and I guess you are not giving me the right answer.  The "other amount" in my donation form is not a calculated field, this is the last choice in the donation amount when our customer cannot find the amount in the suggested donation amount, they can input any amount they want.  I have integrated all the donation amount ($25, $50...) except for the OTHER AMOUNT which should be integrated to paypal so that we get the donation.

I cannot do another paypal integration just for this field of donation.

I understand that you want to have a custom amount as a choice along with the fixed amount to donate. If the amounts are added as products, the received amount cannot be marked as a donation in your PayPal account. The option "This is a donation......" to be selected in the payment wizard.

You can use the radio buttons to display different options with the fixed amounts allowing other options.

The value of the radio button can be sent to the calculation widget so that the same can be used for PayPal.

Please see the demo form below and clone the JotForm to your account to see how it works.
