Hello

I can't seem to find if this can actually be done but, using Excel 2003, I
have a worksheet with several blocks containing cells numbered from 1 to 100.

From these blocks, I want to be able to count each cell as a value of 1 if I
change the background colour to red (or any other colour) then multiply that
value by a number, say 5.

eg If I select the first 25 cells and fill them red, I want my "total" Cell
to show the sum of 25 * 1 * 5 giving me 125.

Hope this is understandable!

Thanks for any help.
