I'll assume you're using the same script as I found.
Read the script carefully, it's written "To Activate: Load Game". So after choosing the script ..
1. Change the value from 0: No to 1: Yes
1.1 Change the value from 9999999 to any number you prefer (I personally change only that Yes/No option for Mood and Smiths Exp).
2. Save your current game then load it up again to activate the script.
(Yes/No means always taking effects. So for the $tarch, don't forget to turn it off)
Done!
