Hi Jay,

The selection has nothing to do with the range you are
picking the max from. The selection indicates the cells
which are to be possibly formatted. See the comments
near the top of the above web page written in RED.
Often you would select entire columns:
Select Column A if you only want cells in Column A formatted.
Select all cells, if you want entire rows formatted.
In your case you have a restricted range for the maximum so
you world probably only be formatting the same range (cols or rows)
Select A1:A10 if you only want to format cells in Column A
Select 1:10 if you want to format entire row on a column A max hit.
In you conditional formatting the formula is based on a comparison
of the active cell (or the offset from the active cell to cells referenced
in your formula). So if you selected A1:A10 *and* A1 is the
active cell.
Conditional Formula 1: =A1=MAX($A$1:$A$10)
But you can use the following instead which allows you to format
the entire row if you selected rows 1:110
Conditional Formula 1: =$A1=MAX($A$1:$A$10)
Every cell that was in the selection when you entered C.F. is tested
with the formula adjusted
A1: =A1=MAX($A$1:$A$10)
A2: =A2=MAX($A$1:$A$10)
A3: =A3=MAX($A$1:$A$10)
...
A10: =A10=MAX($A$1:$A$10)
If you wanted the entire row formatted, then you would have
selected rows 1:10 when you entered C.F., and the formulas would test
all cells in Row 1 test for: =$A1=MAX($A$1:$A10)
all cells in Row 2 test for: =$A2=MAX($a$1:$A10)
all cells in Row 3 test for: =$A3=MAX($A$1:$A10)
....
all cells in Row 10 test for: =$A10=MAX($A$1:$A10)
If you wanted to highlight each new maximum you could use
conditional formatting of so that the upper cell range of the
MAX function varies as the row changes.
=$A1=MAX($A$1:$A1)
