So right now [0-9a] is only going to match any character that is a number from 0-9 or a, so essentially you're matching each single character as a match. so: [0-9a] matches 0 [0-9a] matches a [0-9a] matches 5 if you're trying to match more than one character, you'll need to define your Regex differently - there's a few ways to do it.

What specifically are you NOT getting a match for?

I think this works: [0-9] ?[a-z] Note that there is a space between numbers and letters.
