I have the sku *part number for each individual item for each sale in column
A. In column B, I have the Qty. sold of each individual sku per order. I want
to be able to total the qty. sold of each sku. As an example 1rst sku in
column A is 41-402*Column A list the sku sold for the sale, column B lists
the Qty. of that sku sold for that individual sale. There are several hundred
sales in column a and the same sku will appear several times with different
qtys. listed in column b. Need to sort and total Qty. of each sku sold .
