How do I correct error using the =IF(AND(formula in excel?

[Redwing ML]

Hello, can you help?

I would like to correct the following formula...This is what I have...

=IF(B1:B4,">=01/01/06"),THENCOUNT,(C1:C4,IF=A1))

This is what my worksheet shows.....

Column A Column B Column C Column D
A 12/20/05 A (Above Formula)..This
should=2
B 12/21/05 C
C 01/03/06 A
D 01/21/06 A


Can you please help me in how to write the formula correctly???

Thanks so much!

=SUMPRODUCT(--(B1:B4>=DATE(2006,1,1))*--(C1:C4=A1))

Are you trying to count how many values in C are = or > 01/01/2006?
If so, =COUNTIF(B1:B4,">=01/01/2006")

If you want to count with more than one criteria (say B >= a date and A = C)
=SUMPRODUCT(--(B1:B10>=DATE(2006,1,1)), --(A1:A10=C1:C10))
(I used 10 rows to test the data; I use DATE since I work with the other
date system - dd/mm/yyyy)

No need for double negatives when you use * operator, only when the two
arrays are set apart by comma as in
=SUMPRODUCT(--(B1:B4>=DATE(2006,1,1)),--(C1:C4=A1))

Thank you again for the help but, it must be me? Iam still trying to get your
suggestion to work completely.

Needed=IF(B1:B4,">=01/01/06"),THENCOUNT,(C1:C4,IF=A1))

Your way =SUMPRODUCT(--(B1:B10>=DATE(2006,1,1)), --(A1:A10=C1:C10))does
count but, if i change the actual date in a cell from B to be less than the
date of 2006,1,1 the quantity does not adjust?

Can you help again??

Thanks
