I have one worksheet that contains Last Name, First Name of an entire
organization.

I have another worksheet in the same file contains Last Name, First Name of
a specific group within that organization. This worksheet also contains 2
other columns of information of that group (courses completed, courses
attempted).

I am trying to combine these worksheets so that the Last Name, First Name of
the entire organization is shown and for those names that have a match with
the 2nd worksheet, the courses completed and courses attempted data is shown.
