Sort and tally Multiple Entries

Hey Everyone,

I'm pretty new to macros and I need to tally recurring entries from a Paypal export by the name to new column for a mail merge for end-of-year donation receipt.

Most donors give a monthly amount and I want to be able to give a total amount in the letter. So the new columns would have the unique name and the total amount of donations by that person.

Any help is much appreciated!
