Maybe the extra "+" by the end of line characters "$" is creating a problem. You
already have one or more numbers defined in the first set of quotes and one or
more letters in the second set, so the "+" outside the parenthesis may not match
up and may not need the parenthesis at all. If the "\r" isn't recognized maybe a
"\n" would instead.
