Ok I looked at all the math functions for PHP but saw no way of returning the average of a set of numbers - I plan on using this for a rating system - any help? -- John

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 +------------------------------------------------------------------------+
