I have to get the user to input data for an item and then when they have done that they can display that information by pressing 2. I get an Exception thrown at 0x7A111F4C (ucrtbased.dll) in ProceduralProjectG00358662.exe: 0xC0000005: Access violation reading location 0x0000004F. It displays the item number and then I get the exception. Any help is appreciated thanks
