Total per item

Do you have any idea on how to get the total of the screenshot1? I need to total the quantity of transactions per item. Please help. I tried to to change its property to:

TotalFields: Quantity

GroupTotalFields: Item No.

and use the footer/body…But I got the result in screenshot2.

How can I get this result?
