I have a work book that looks at usage. There are two sheets. Sheet 1 contains usage data for 1 month. Sheet 2 contains usage data with no restrictions. The data is generated by a data connection to an Oracle database.

Here is what I am trying to accomplish.....

On sheets 1 and 2 there is a Nomenclature Key. For each key that is on sheet 1 there will be a coresponding key on sheet 2. For each time the key appears on sheet 2 I want to get the average of the total quantites. I have attached a small sample of my sheet and what I am trying to accomplish.

So for C3 in your sample, you want a formula that does this:
1) Checks the nomenclature key in B3 (that's 243, in this case)
2) Finds all the rows in Sheet2 that have that nomenclature key in col A
3) Displays the average of the corresponding values in col B

Right? Seems to me you want COUNTIF and SUMIF. No, wait, I just looked it up; Excel now has an AVERAGEIF function, so it's even simpler. I've never used it, but according to the documentation it should go like this:Which says "Look in Sheet2 col A for any rows that equal B3, and for those rows return the average of the values in Sheet2 col B".

Thank you very much. The Formula works exactly as I need it to. However, I asked the wrong question.....

Thats how it usually works for me.

There will be a new post with the updated questions.

Thanks again.

LOL! It often happens that way; once I see the answer, I realize I asked the wrong question. Well, someone will be here.
