using a list to return a value from another column

[Greta]

I want to use a list (column B) to restrict data entries into a spreadsheet.
However, I want the list to return a value in a different column (column A).
For example:

BH Borehole
AR Air

I would like the list to show the real-world names, but the data that is
entered into the cell to be the associated code. This is a DB interface
tool, for an existing database with specific fields already setup, so I
cannot add columns.

Thanks!

If you can't add columns then you are in a spot of trouble. You could use a
macro to update the word to its associated code but that will require custom
written code. The code is not distinctly difficult but it will probably be a
bit over your head unless you are familiar with VBA...
