I thought it might be something like that. I changed the columns to no
decimal places, but since it was getting data from an external database it
might have caused the problem.
It's working right now...if it stops I'll be back!
Thank you SO much for the help! I was really in a corner.

Define "working".


=IF(AND(HI2401,HI2<402),"YES","NO")

It probably has nothing to do with time of day, unless the value in H12 is
derived from time of day (i.e. NOW()).

More likely, the value in H12 is not what it appears to be. For example, if
the value is 401.00001, it might be displayed as 401, so you might expect
"NO". But AND(401<H12,H12<402) returns TRUE, so you actual get "YES".

If that is not enough to help you, post again with details, namely the
formula and value in H12, formatted to 13 decimal places.

Excel 2007 is what I'm using

=IF(AND(HI2401,HI2<402),"YES","NO")

Thank you in advance for any help you can give me.
