Using the example below, I need a worksheet formula that will
automatically
determine the number of blank cells in column B based on the number of
rows
in Col A containing entries, which can vary as more entries are added
after
the last row. So the formula needs to automatically determine that number
of
rows in column A for the whole column, not just a select number of rows.
In
this example the number of rows is 5. Fortunately, the first null entry
in
Col A will indicate the end of the data in that column. So there are no
nulls in Col A before the last entry. In my example, the answer is 3 (for
nulls found in Col B rows 2, 3 and 5). Any ideas? Thanks in advance.
Col A Col B
Row 1 10 X
Row 2 20
Row 3 25
Row 4 100 x
Row 5 15
