I am not much of a programmer I have been self taught from building sketches and some online tutorials as well as taking apart others code and seeing how it works but some times I can't see the obvious. So I would appreciate any help below is the error I keep getting and the code.
Arduino: 1.8.12 (Windows Store 1.8.33.0) (Windows 10), Board: "Arduino Uno"

This example code is in the public domain.
the segment you want to show has to be HIGH
the digit you want to display has to be LOW
