Sum If - How to sum for ranges meeting certain criteria

[Corrina]

I have the following data:

Col D Col E Col I
Part Numbers Part Unit Cost Extended Value


Question 1: How do I sum the number of unique parts in the following ranges
(<=$25, $26-50, $51-100, $101-$500, $501-1,000, >$1,001)? I was able to do
it by part, but not unique part. I am trying to avoid duplicates.

Question 2: How do I sum the dollar value associated with those ranges? So
I would be able to say I have 10 unique parts in the <$25 category, with a
total extended value of $XXX (this should include the duplicate parts since I
am trying to get a total value).

I have been playing with this and can't seem to get it to work.

Thanks,

Do you want a SUM or a COUNT?

Can you post a small sample of data and tell us what result you expect?
