Would somebody please assist me? I have been consistently been doing trial and error with my counter. You see, when the program cannot locate an item (which is typed at the bottom) it displays "Sorry, no such item number exists, please enter another one or 0 to stop." Every time I try to locate the first few items it loops back into the same message, whereas when I type the last item number on the list, it can locate it... And if I type a 0 in when it can't locate the number the total adds up to a really high number.
I don't understand why this occurs, but if someone would like to help, I'd be happy.
