Not necessarily. I want to end up with "Files (7)" or whatever number it
happens to be as my variable value.  Then I'm going to run a check on
it.

I'm a beginner and this is way too complicated for me to handle.
Isn't there a simpler way? $ie.text will grab ALL the text on the
browser page, but I just want that small bit.
