Ankit, You are correct. It works fine without the backslash comma (\,). I made an invalid assumption that I would have to escape the comma and the tool I use to validate regular expressions only appears to allow a dot (.) or comma (,) and didn't complain about the \.\, value.
Thanks, David Morris >>> [EMAIL PROTECTED] 8/9/2004 3:15:19 PM >>> David, The second expression "[0-9]{18}[\.\,][0-9]{3}" is still invalid since you cannot escape a comma. Try running without the comma escaped: "[0-9]{18}[\.,][0-9]{3}".
