I am working on a spreadsheet that when I enter or select certain
information, other column and line info needs to change (always the same
info) too. For example: I enter a name "joan" in A2. B2 needs to have a
certain rate for Joan, and G2 has a certain other piece of info ALL
PERTAINING TO JOAN. This is a spreadsheet that I am creating.

What is that called and how do I set it up?
