Hi,

Just been experimenting with Cascading Selects, and have the example  
working well, but have been trying to group 3 choices together on one  
screen. In this case Family, Genus and Species (as a field-list), at  
present it does not like it (selection does a little wonky). Does anyone  
know if cascading select will work as the same time on the one screen  
(using group and field-list), anyone have an example I can borrow?

Many thanks

No, I do not expect it to work.

When field-list displays were introduced, we decided to not apply  
constraints across questions shown on that one page. So if Q1 makes a  
selection that Q2 must then use to produce a filtered list of choices, then  
you MUST NOT place Q1 and Q2 within the same field-list group.
