Check the cause of the incorrect total reported by the user when checking the application and report on their side
as per checking, the cause of the incorrect data is duplicate data, discussed this with sir Ian, then he deleted the data and as per checking, the total for quantity is now tally, but not the retail total
check the cause of this, as per checking, the cause of this is that the retail is added to the total even the sold qty is zero
add formula to the report to exclude the retail if the quantity is zero, give updated installer with Sir Ian for testing on his side.
