I don't understand why it won't verify - I am trying to update the file but it removes all the content - "-u", "19847 ", "Swim trunks, blue ", "159.00 ", "20 "The program won't verify, I have tested it with a file that has the example given and the argument "-u", "19847 ", "Swim trunks, blue ", "159.00 ", "20 ".
The program runs but the file is empty.
I don't understand why it is empty because I have checked the program and it seems ok.
