I've been racking my brain (and the forum) with this one for a couple days now, so I humbly submit to the all-knowing RocketBrain.
How can I pass custom values through to the "Purpose" (or Prouduct Title) field in PayPal?
I have a donation form, and a separate subscription form, where user's can select the gift amount and designation, but all that is passed through to PayPal in the purpose field is "$[amount], Specify Amount, Select Fund" (respectively, the amount they selected, a label for a hidden field for other, and the "select fund" label). What I'd really like to see instead is "[Specific Fund Selection]"
I'll happily switch to Product fields over donate fields if that will help solve it.
