I hope someone can help me with this:

I have a list of TYPES of users, each with a unique ID code and three
numbers associated with that ID code. I also have a list of unique users,
each with one of the ID codes.

Is there a way to match the correct three numbers to each user on my user
spreadsheet, perhaps without complicated visual basic programming? I wrote a
macro that will make this work, but I'm hoping to use a technique that is
more friendly for my coworkers.
