This should be easy, but I can't find an example ANYWHERE on the web! I just need to know how many numbers are chosen in a text box.
EXAMPLE: user enters the following:
101-105, 107, 109, 110-115

How do I calculate that this should equal: 13

Thanks,

Mex

If there is a planet called JavaScript then Charles must
