Alice it seems hard to help as you have been essentially posting the
same code, with the same error for weeks,
When you go
for $ad in distinct-values(...anything)
then, on each iteration $ad will be a single string (one of the values)
So on each call to local:distinct($ad) you are passing in a single string. so
doing operations such as distinct-values() or for or order by are all
essentialy null-operations. It's not an error to take all the
unique values from a sequence of length one and then sort them, but you will always
just get back the value you started with.
