I'm trying to do a logical test that uses dates. If I use it returns the
correct result, but if I use = or < I get the wrong result:

A B C
1 25/03/2010 500 0
2 24/03/2010 300 0
3 27/03/2010 750 750

In C1 the formula is =IF(A1=25/3/2010,K32,0) which I would expect to be true
and return 500, but it returns the false value
In C2 the formula is =IF(A2<25/3/2010,K33,0) which I would expect to be true
and return 300, but it returns the false value
In C3 the formula is =IF(A325/3/2010,K34,0) which is true and returns the
correct value.

Can anyone help?

Excel sees 25/3/2010 as a multiple division, not a date. Use either this...

--"25/03/2010" (Note the double minus sign in front)

or this...

DATE(2010,3,25)

=IF(DATEVALUE(TEXT(A1,"dd/mm/yyyy"))=DATEVALUE("25/3/2010"),K32,0)
=IF(DATEVALUE(TEXT(A2,"dd/mm/yyyy"))<DATEVALUE("25/3/2010"),K33,0)
=IF(DATEVALUE(TEXT(A3,"dd/mm/yyyy"))DATEVALUE("25/3/2010"),K34,0)

You're comparing with 25 divided by 3 and then divided by 2010.

Others have suggested --"25/3/2010" or DATEVALUE, but if you have a date
like 4/5/2010 you have an ambiguity as to whether this is 4 May or 5 April,
and this is determined by your Windows Regional Options (in Control Panel,
not in Excel), so you're better with an unambiguous definition
DATE(2010,3,25).
