I sorry I do not understand what you are saying. All 2015 Q26 is a number I calculated by just putting in the cells. I had a formula that looked at the date in column I and cost in column J and put that in the right cell under the right month in cells S, U, W and so forth. And it total all the cost for that month.

I can give you parts of the formula.

=Product it had $I11:$I30 it also had $J11:$J30 it also had <Name Year Month>
