I'm using excel 2007 and wish to add a Function that makes use of regex. I see in the documentation for regular expressions that I
need to add references to Microsoft VBScript Regular Expressions
. I don't know what this means or how to do it. Can someone enlighten me?

I apologize to ask this question, but I have used search engines, and inclusion of 'reference' in my search terms usually turns up an API sort of doc or else something on Microsoft Visual Studio.
