You can't automatically insert the values from a dynamically-built / indexed value list into a static value list.
you can run a similar query using filemaker pro advanced data viewer, and filemaker 12's executeSQL function.
If you have both of those, you just need to open the data viewer (tools > data viewer), click the "watch" tab, click the green plus sign to add a new watched expression, and enter your ExecuteSQL query:
ORDER BY value ASC
" ; "" ; "" )
Click "evaluate now", and you will instantly have a unique value list (alpha sorted), of which you can copy and paste the values from into a static value list. Furthermore, you can click "monitor" to continue to monitor this calculation for later use, just re-click "evaluate now" to refresh the results.
Thanks very much! Mike
