How do I set conditional formatting to compare cells in 2 columns in Excel 2010?

Hi,

I am trying to set conditional formatting in column B based on if $B1>$A1 and each corresponding cell down the column.  When I enter this formula, highlighting the amounts in column B, the result is based on comparing to only cell A1, no matter what B cell I'm in.  For example:
A      B
45      90
90      88
78      77
91      95
50      46

The result should have only column B's 90 and 95 formatted.  Not all of B's numbers.  

Appreciate the help!

Pat

Hello Pat

I selected column B and then applied conditional formatting with that formula (see attached). It seems to work as expected

I think a possible cause of the error would be if you have a header row in row 1, but your data starts in row 2.  If your formula is =$B1>$A1, but you've highlighted cells B2 on down, you'll get undesirable results (it would be comparing the previous row in each test).

If this is the case, just go to the Manage Rules option under Conditional Formatting and change the formula to $B2>$A2
