Optional Payment (Donation)

Hi,

I would like to know if there is a way to only send the user to Paypal if they choose to make a donation? (i.e. if they check a text box “I would like to make a donation”). Is there anyway to make the payment conditional / optional.

I know they can submit the form, and they will get redirected to Paypal, and they can just not complete the process. The problem is that is confusing, especially for technically challenged users. Also, we don’t want to make the user feel obliged to make a donation.

Any ideas?
