On a page I'm working on, I have 4 dynamically-created strings I'd like to compare...each string is just a comma-separated list of up to 20 different numbers. What I want to do is to find all numbers that appear in more than one string, and then make a new array with just those numbers, sorting by numbers which appeared the greatest number of times first. I'm way too retarded to figure this out, can anyone help? mhat@samplehead.com
