I'm creating a Unique filter of users starting from I11. This list
can be from 1-20. In J11, I'm creating a average time spent for each
user.

How do I create an autofill range that only fills as long as the
Unique filter range?

I know I could use Range("J11:J" & counta(I11:I30).FillDown, but
that's not working. How do I tell it to start in cell j11 and count
down the number of cells filled in range I11:I30?

Thank you in advance for any help.
