I'm trying to apply conditional formatting to a cell, to show it has expired
when today's date equals the date of expiration.

I have the =today() formula in a cell for reference, however the
conditional formatting changes immediately even though the two cells are not
equal..

What am i doing wrong??
example:

cell A2 is the date of expiration- 7-1-2012
cell G5 is today's date- 8-15-2008

when they are equal to each other, the conditional formatting should apply.
