I am afraid that doesn't work. The first one is appearing in all of the letters no matter what fund they donated to. To clarify a bit more I hope, If the fund equals one of the seven funds they can donate to, special wording about that fund will be inserted into the letter, it won't say the word ART etc, I just wanted to keep it simple for the test. Unfortunately, I can't not put the year this is technically a tax receipt with an acknowledgement piece attached.
