Incorrect error message displayed

[Thunderdragon221]

• A different case of incorrect error message displayed
• When adding an order via command "6", when 0 is entered as the quantity, the error message displayed is "Error: Quantity must be a number", which does not make sense and confuses the user, since 0 is indeed a number.
• Correct error message should be "Error: Quantity must be a number greater than 0".
• Since this confuses the user and makes the user doubt the application functionality, the bug severity is medium since it negatively impacts the user experience.

Team's Response

Although we accept this as a bug, we feel that the severity has been misjudged.

On typical usages of our application, we do not expect quantities to be less than or equals to 0. However, we understand that we should have make the error message more specific.
