Hi all, I want to write regular expression for checking the string format entered by user. the allowed formats are examples: 10 10, 10,12-10 12-10 that is the valid strings are: 1. only integer 2. an integer, range of integers example 3 and no other characters must be allowed.ereg("^[-0-9,]+$"... would do it, but it would also allow "10,-" as a valid expression as well.. so if you want to check for valid ranges you'll want to beef that up a bit... -philip
