hello!
this is my first post EVER! so please be kind. ive searched everywhere on the site to try to find an answer but nothing...
so here is my setup:
i am building a school scheduler where the user can see assigned "rooms", "periods", and "class". these 3 fields are on a table called "scheduler". And each of the fields are foreign and grabbed from their respected tables.
what i need is validation calculation for each field (rooms, periods, class) that examines that no record creates duplicates.
the tricky part is this:
- a "rooms" can have the multiple "class" but not the same "period".
- and vice versa, a "class" can have multiple "rooms" but not the same "period."
example:
Room 100 = Class 4A = Period A
Room 100 = Class 5A = Period B
Room 200 = Class 5A = Period A
Room 200 = Class 4A = Period B
thanks in advanced for the help, and i really hope i made sense. }:|
