Nope - you'll have to 'roll your own' by looping though the set, or (if you have version >= 4.0.5) you can use array_reduce() in conjunction with the count() function. If these values are coming from a database, most databases have aggregate functions to do sums, averages, etc. -steve +------------------------------------------------------------------------+ | Steve Edberg [EMAIL PROTECTED] | | Database/Programming/SysAdmin (530)754-9127 | | University of California, Davis http://pgfsun.ucdavis.edu/ | +---------------------- Gort, Klaatu barada nikto! ----------------------+
