Yep, that's exactly right.
I want to name AU_1, AU_2, ..., AU_5 as "AU".
The way I want to recall or validate this name range is as follows:

a) 1st column is a list of different teas
b) 2nd column is specified by the user - this is formulae driven and so there is no data validation
c) 3rd column is where the data validation takes place and where I originally wanted to use =indirect("AU") to give me all the different options AU_1, AU_2,...,AU_5
hope this makes it clearer. Thanks!
