Hi,

Sure, try something like this

=SUMPRODUCT(--(A1:A5=D1),--(A1:A5<=E1))

Where your data is in range A1:A5 and you enter a lower and upper bound in
D1 and E1.

Dynamic!

If this helps, please click the Yes button.

Can I freely set a range criterion(a) for counting? e.g. for the following
data, can I set < 80 or 100 or <120 and 80 DYNAMICALLY? I can do that by
adding columns to check the conditions but it then constrains my mind as I
cannot see the statistics in real time. Thanks.
