It doesn't look like any of those entries are in cell A1.
What you want to do is first select the ENTIRE range that you apply the Conditional Formatting to.
Then, write the formula as it pertains to the very FIRST cell in your selection. Excel will adjust it for the rest.
So change all those "A1" references to the address of the first cell in your selected range.
If you are selecting cells D2:H3, then write:
Code:
[COLOR=#333333]=OR([/COLOR][COLOR=#ff0000]D2[/COLOR][COLOR=#333333]="1/3",[/COLOR][COLOR=#ff0000]D2[/COLOR][COLOR=#333333]="3/3",[/COLOR][COLOR=#ff0000]D2[/COLOR][COLOR=#333333]="10/25")[/COLOR]
