valuelist from field? how to avoid repeated items?

[gwjo]

Hi,

I'm having a real problem that makes my head hurt!

I'm trying to set up a value list that uses values from a field - e.g. field1 = make of car, field2 = model, so that the value list for field2 depends on the entry (from a static valuelist) for field1.

I've set up a series of global fields with all the possible values for field2 and defined a holding field as a calculation based on the value for field1. This seems to work in that the holding field correctly returns the values from the appropriate global field but it doesn't work as a valuelist in that it returns spurious values from more than one of the global fields.

Can anyone suggest where I am going wrong and /or show a worked example of how to do this correctly, please? (FMPro8 help is beyond me on this one - seems to be littered with circular arguments that I can't follow)

Many thanks

George

What you're after is known as a "conditional value list". 3 examples that may help you below.
