Combine values to equal one DB key number?

I'm setting up a database in which users would enter data using a file with
multiple forms, which when finished will be appended to the "master"
database. I was wondering if it is possible to concatenate two values to
equal the DB key number. Problem is, I'm not sure how (if possible) to
perform this within a table. In other words, I need to combine two value to
equal a third value, all within the same table.

Any ideas? Thanks!!
