Changing allowed time

[Hugothalen]

Hello,
First, thank you for creating and sharing this script. It's desperately needed in my house. I'd like to edit the script to make weekdays 60 minutes and weekends 120 minutes. I can see the spot in the code to make the changes, but I continue to receive error messages saying I don't have permission to edit the file. This is through the text editor using an admin account. I tried opening the file for editing through terminal and it's demanding a password. Is there a way I can make these changes, or is it locked to the default settings.
Thanks.

You might need to use the chmod command.
