I am just playing around now after finishing the project since.
I set up and entire string with the media type, the title, run time/pages,
author/director/artist, what it is rated, and whether it is checked out or available for when I call printString().
I am running into an undefined at the end and the printString at the beginning.
can anyone help me fix this code?
