Multiple Unrelated Tables Access 97

I have an Access 97 database with two tables. One Table is Clients the other one is Volunteers who might help a client. I made a clients form and put a button on it. The button takes you to the Volunteers form. Now I search around and find an appropriate volunteer. I want to capture that Volunteer’s First & Last Name and be able to put it in a field on the Client form.
Any ideas would be greatly welcomed!

Thanks,
Alan
