We need to pass information to PayPal using their Comment1 and Comment2 fields for accounting purposes. We have several units using the cart for different fees and our finance team needs to be able to see and sort by the units in question on the PayPal Manager website. The Comment1 and Comment2 fields seem to be the ideal place to pass this information to PayPal, but we can't figure out how to populate and pass these fields to them in the module code.
How would you recommend accomplishing this?
