Suppliers----<Suppliers_Locations>-------Locations (It's really not a good idea to use a math operator such as / in a field or table occurrence name.)
On a SUPPLIERS layout I have a portal showing each suppliers different locations.
Is this a portal to the join table? (Suppliers_Locations).
I need a dropdown list first for choosing the LOCATION state, which then using a conditional value list will list the LOCATIONS towns in the next portal field.
Do you have a table of towns linked to locations?
Locations::__pkLocationID = Towns::_fkLocationID
If so, you can define your value list to list values from Towns, Include only related values, starting from Suppliers_Locations.
