I installed the add-in and the RCHGetTableCell function is working
fine.... beyond my imagination that even this can be done. However, it
does not satisfy my criteria.

When I type =RCHGetTableCell("http://mywebsite.com/page1.htm",
1,"Report Owner:"), it gives me "Error" because it will not go that
page without proper authentication. In order to go to page1.htm, you
have to get authenticated by the http://mywebsite.com/ using a valid
username and password.

Best bet would be to read over at least the "Overview" document in the
"Documentation" folder. Current version of the add-in can be found in
the "Add-In Files" folder. None of the functions or macros will work
until after you've downloaded and activated the add-in.
