The only part i'm interested in/having difficulties with at this point i the last part... " i've created these tables and the relationship in Tools, Relationship, and then tried to create a form but when i got to input info through the form, i can input the first date and the FKDate control appears as 0 (zero) which is correct and corresponds to the first IDDates value. Then, i can continue to input new records alright. But, when i try to input another date, the control will accept it, but when i change to the Visits area, the FKDate field doesn't increment to a new value, it remains zero. What am i not doing correctly? Or is Base not capable of this type of input? " Have a great afternoon! :)
