The parameter is hardcoded. I don't want the path to the script to be hardcoded as I want it to be able to reference itself no matter which directory it's in. The '$loc' parameter is hardcoded. That's the error I need it to spit out if '$loc' wasn't valid.
I want the error to say "You specified a target that wasn't valid and here's the line number of that invalid target" basically. The script needs to be able to do that no matter if it's in /var/root or /var/foo/bar/lorem/ipsum/dolor/we/are/the/world/we/are/the/children/
