How to make a payment form with products and custom amount

I have a client that received stated amounts for PayPal payments but then one filed that is the applicants choice of funds.  How can i incorporate that into the same form?

Hi,

There's no direct solution for that but there's a workaround.

You just have to add a separate product with a base price 1, then name it e.g. "Custom Amount" and add Custom Quantity (Text Box) in it. So whenever the user enters custom amount of  e.g. 25, it will be added to the total amount.

Here's a visual guide:

Then add Custom Quantity (Text Box).

Example:

Note that I have injected CSS codes to this form so the check box in the custom amount product will not be shown. If you need help formatting your custom amount this way, let us know so we can assist you.
