Usually you need to group on something for a max to work (at least in Oracle)

First, how do you know your query is returning a FALSE result? What test are you performing and what are the results of the test? Second, what type of column is fee_recd? I've been toying with the MAX() function on the command line with a number of my own tables using different column types (DATE, TEXT, VARCHAR, INT) and have yet to see it fail to return some sort of result set.
