Hello everyone, I think I may have put something up about this before, but the problem is amateur radio call signs get reallocated from time to time when a person has passed away, and a while later as reallocated to a new person to keep track of this sort of thing I should put all call signs in a separate table and use a query to put it into the form and on the table. I was thinking about it would have start date end date it was allocated to a certain person you would need a query. I am guessing to select the person's name, which originally had the callsign like my father and now it's allocated to another person any suggestions on this idea would be greatly appreciatedI am starting to work with level I expert and I may run into Cobham's with joining tables and a query. If so watch out for any messages from me. If you are able to thank you again
