Regular Expressions

  #1  
Jul 26th, 2005
ok, new to regular expressions so can someone please explain something to me. In trying to create an expression to check if an entry is between 1 and 15, I first came up with:
[1-9]|1[0-5]
this didn't work however
1[0-5]?|[2-9]
did work.

I understand why the second one works, but not why the first one didn't.
