Please am designing a small Inventory, and if the amount stored of any item is equal or less than zero. only I want to disable removing items from store… and allow the only addition
I have two columns (Operation,Amount) , the first one store’s operation type(adding, removing)
the second stores the amount to be either added or removed.
so if the operation is removing and the total amount stored is equal or less than zero, i want to disable the second filed (amount)
