Youre right
This snippet inserts a Countif formula in col AF (at row r+1)
Countif takes 2 arguments the range to check and the critiiria
rngbas.address is the reference to the cells to be counted (must be defined
earlier in the code)
cells(r+1, "AE").address is a reference to a cell that contains the criteria
on which to count them

I think this means that a formula is being inserted in cell (r+1,af).
The formula is counting all of the occurrences of the contents of cell(r+1,
ae) that can be found in a particular range.
I know that rngbas is a range.
I do not understand the rngbas.address or the second mention of .address.

Please interpret for me.
