Newbies Daniel Esposito Posted July 5, 2003 Newbies Posted July 5, 2003 Hi all... I have the following problem: I have two databases which are related to eachother. DB one contains 5 different fridges as items. DB 2 is my main DB to record new entries for leasing one of these fridges to a new client. The fridges are linked to my main DB with a dropdown menu to be selected. My question is: How can I prevent selecting a fridge that's currently allready leased to someone. Is there a way to do that? Perhaps by locking the leased fridge and diplaying a popup message? Any help would be greatly appriciated!! Thanx!
ernst Posted July 5, 2003 Posted July 5, 2003 I suppose that the Lease database DB2 has a record for every time a customer leases a fridge, with a field for selecting the fridge that gets leased, which I will call 'FridgeName' and a date field that gets populated when the fridge returns. I'll call that one 'ReturnDate' You could give each record a calculated field with the following definition: [case( not isEmpty(ReturnDate) , FridgeName)] Now use a value list that gets it's entries from this calculated field and Bob's your uncle! Hope you get the idea, Regards, Ernst. (going to take a look in the fridge, thirsty)
