=if(and(401<=round(HI2,0),round(HI2,0)<=402), "YES", "NO") would presumably
be equivalent to
=if(or(round(HI2,0)=401,round(HI2,0)=402), "YES", "NO") or to
=if(and(HI2=400.5,HI2<402.5), "YES", "NO")
if either of those helps the OP to see whether that's what he wants.

[I have changed your H12s to the OP's HI2 reference.]

I think you missed the point. Changing the format only changes the
appearance of the cell value; it does not change the actual value.
WYSI(not)WYG!


You wrote previously:
=IF(AND(HI2401,HI2<402),"YES","NO")

If you are happy with displaying H12 with zero decimal places, it is no
longer clear what your intent is with the AND() expression above.

I suspect you want:

=if(and(401<=round(H12,0),round(H12,0)<=402), "YES", "NO")

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.
