Hi CRR,
The field you put in your GridView report is actually the Qty of Lot 1, not the total qty. There in fact is no stored value for Total Qty in the database, which is why you cannot see it in the list of fields.
What you need to do is create a Calculated Column and sum all 5 of the qty lots to arrive at the total Qty on Hand.
