Hi Sara
Supposing cell A1 is the cell with the date, and you want to test whether it
is equal to Today().
Supposing B1 is a cell where you set Conditional formatting
In B1 the Formula is =$A1=TODAY()
When 19/02/2008 is type in A1, your cell B1 will change to the require
colour.
Now, select B1>double click the Format painter (to make it sticky) then
click on cells D1, H1 etc and press Esc when you have finished.
Cells D1 and H1 will have the same Conditional formatting that you applied
to B1
This will only work, if you have made at least the column Absolute with $A1
not just A1
You can have three conditions applied to cell B1 to give your three colours
dependent upon the cell value, and provided you have "anchored" column A
with the absolute dollar, all three formats will be painted to any other
cell you choose.
