Hi Please find the updated code -

Only UpdateNumber function need to be change.

Blist[i].SetQuantity(GetQuantity() + num); -- This line need to be change.

Because GetQuantity will run only with Blist[i] and without any argument.

Book:GetQuantity will not take any argument and  will get the current value of quantity to Quantity variable.

same as

Book:SetQuantity will not take any argument and will append the current value of quantity to Quantity variable.
