Hello all! My apologies if this has been asked (especially multiple times).
I'm building a platform that would allow users to see how their charity donation breaks down by line item (ex: amount going to clothing, amount going to water, amount going to food, etc.), and then allows them to donate that value in a lump sum via a PayPal button. I'd like the user to be able to click the button and have the amount they selected be pre-populated in the donation screen.
There aren't specific line items on the receiver end, this is more a calculator meant to encourage informed donations (like if you wanted to make sure to donate enough for clothing for three people).
