Conditional Formatting on Excel 2010

Hi,

I am trying to figure out the correct method in which to apply a formula in conditional formatting. The first row contain the document names. The coulmns row contain due dates in a weekly calendar format. I want to highlight the document cell(in the first row) according to the due dates, if they fall within due date, one week, or one month in the specific row of the document cell. Ex.
Week
Document Jan 5 Jan 12 Jan 19 Jan 26

A Jan 15
B Jan24
C Jan6

What i would like to do is have the formula go through the row for Document A and see if there is a date matching today's date. If there is then I would like to Higlight cell that contains A.

The current formula I am using in conditional formatting for the first document A cell is:

=$E$3:$G$3=$B$27 [if true it will higlight the specific document cell red, B27 is today()]
I feel this formula should go through the dates in that row and if it finds a date that matches it will highlit document A cell.

Currently it does not work. It works if I change the above formula to specify each cell in the row but that would mean creating 100 formula's. Is there another way.

Thanks
