Need to add a radio button in Paypal Payment Field

Hi

I want to need redio button in paypal amount 

I want to give option to user select $10, $25, $50, $100 and last option for other amount and if user select other amount option than he can enter amount 

Is it possible form your side 

You can add a Single Choice Element and add the amount options. Then, toggle on the "display other option" for the user to add his preferred amount.

Next, add a Form Calculation Widget to calculate the total amount from the single choice field. Here's the guide on How to Perform Form Calculation Using a Widget.

Lastly, you need to pass the total amount on the PayPal Payment Field. Here's the guide on How to Pass a Calculation to a Payment Field.

Hope this helps.
Regards.
