I have an eight-column Excel (for Mac, but don't think that matters)
sheet (i.e., columns "A" -"H") and am trying to write a macro that
will look down the cells in Column "H" (about 10,000 rows of data)
and, upon finding an empty cell ("target cell"), copy the contents
(text) from the cell directly above that cell IF:

--the "target" cell is empty; AND
--the value of the same-row cells over in column "D" equal each other.

In other words, an example:

IF. in Column "H", Row 26 has a value of "Judge12", and Row 27 is
empty, the macro should copy "Judge 12" from Row 26 to Row 27 in
Column "H"
AS LONG AS Rows 26 and 27 Column "D" both have the same value, e.g.,
"Smith."
