>I am trying to set up a date base and relate it to a field in another database, ie: a date field. The First database is an inventory of equipment with a last serviced date field. I want to create another dbf that will have the same equipment Id# and several date fields that will update every time I update the date field in the first database, thus giving me a running record of service with out cluttering up the main database or having to do entries on each database seperatly.

Actually each time first table' field gets updated your application must fire some procedure which will scan second table using equipment id and reset values in date fields (using your algorithm). Hopefully 2.5 supports UPDATE command which will solely do this job. If you something behind the scene move to VFP with referential integrity triggers.
