Thanks. I have already seen the user guide and had actually been working from that second example. What caused me to believe it may be possible to use the code from the second level selection was that in the example pains are taken to actually define it. Why, I thought, define Code2 as Field1+' | '+Field2 unless something uses the value?
It is unfortunate that it also suffers from silent failure when not applied.
I can see why it would work that way for ease of implementation. But if only the field value were set at each selection level, it would have worked!
