@Lisa2045 You didn't specify the entire formula and it seems you are working with structured table references. And perhaps some quotation marks and brackets were included accidentally. Having my doubts about the table name as well as in my Excel it's not allowed to use any other special character than an under score "_" in the name. So, check the table name and try this:
=SUMIF(Donor_List[Years of Support],">15",Donor_List[Total Annual Donations])

@Lisa20451545 Sorry. Don't know anything about the book/course you refer to.
You wrote "that did not work so there must be an error somewhere ...". That's it? Without an example of the Excel file where the formula is supposed to work, there's no way to tell what's wrong or why.
