Chuck,
If your running Access 2003 or later you can make use of the built in option for viewing object dependencies, this requires you to have turned on Name Auto-Correct. To do this simply select your object -> View -> Object Dependencies. However having this Name Auto-Correct feature turned on has reported to cause problems for Access to the extent that it is recommended you turn it off!
An alternative solution can be found at this link
Documenting query dependencies in Access which involves creating tables then running code that collates dependency information writing it to a table.
Hope this helps,
Dave
