If YourFormula is =SUMPRODUCT(--(ColorIndex(B9:U11)=3))*14
then Arvi is suggesting that you try
=IF(NOW()=NOW(),SUMPRODUCT(--(ColorIndex(B9:U11)=3))*14)

Thanks Arvi

However, I am sorry but I do not understand quite what you mean and what
to
put as the formula!

Hi

Changing background itself doesn't force recalculation (at least in
Excel2000). Try this:
=IF(NOW()=NOW(),YourFormula)

Worked fine but.....

If I remove the red background or add more cells to the "red" list, the
calculations do not change, the total stay as it was.

eg =SUMPRODUCT(--(ColorIndex(B9:U11)=3))*14 returns the value 140 if
I
make the background RED for the first 10 cells.

If I then change the background of any of these cells by removing the
RED
or
if I add additional "RED" cells, the total value is not changing.

Again, am I missing something here.

Thanks
