dbcontrol.mdb? how to use with normal tables?

[mheilbut]

I have here in my company some information that come from the production of the machines which go through a collector and throws the information in a .mdb database. I have a crystal report with normal sql tables but need to use a field in the .mdb database. I can get the table I need in the crystal table area but don't know how to join the tables. Can anyone help me out with this?
Thank you. Michel, São Paulo, Brazil
