No you weren't misunderstanding. In the past on this board sometimes suggestions made to problems have been rejected as no good when they clearly work for the person suggesting the solution, ...and sometimes the problem is that the suggested solution has not been applied exactly as instructed. I was just trying to ensure that wasn't the problem here - hope you are not offended by my checking.
Again just double-checking:
1. Confirm that the formuls you quoted
Code:
(=MOD(SUBTOTAL(3,$A$1:$A1),2)=0)
in fact does not have the ( ) around it when used in Conditional Formatting?
2. Confirm that the above quoted formula is from the Conditional Formatting from a cell in row 1 only and that a cell in row 3 has
=MOD(SUBTOTAL(3,$A$1:$A3),2)=0
3. Confirm that it is alternate ROWS to be shaded, not alternate columns. This question asked because of this from your last post
the goal is to filter on column B, and have columns A through H colored alternately
I am using Excel 2003 but as far as I know the suggestion should also work in Excel 2000. I confirm that when I filter on column B (or any other column) the visible rows of columns A to H are coloured alternately.
I am running out of ideas as to why yours is not working. One thing that may be worth trying is to start a new sheet in a new workbook, put some data in manually (not formulas) and apply the suggested formatting again. If this works correctly, it might at least point the finger at your aother workbook or worksheet rather than the version of Excel or anything else.
Good luck!
