Good catch, To-Liang! It was due to our program's previous lack of a storage checking mechanism. I have solved the bug by enabling the system to check if there are enough goods in storage to sell whenever the "Sell Inventory" method is triggered. Now, if the desired amount to sell exceeds the current available amount, the system will not allow any alteration to the inventory storage and will instead show an error message notifying the user of the shortage of goods to sell.
