Hey Andrew, were you clicking the "Run" button on google apps script? That would cause an error because there is no onEdit range. This script is triggered via an edit. If you want to test the script, there's a way to debug the trigger at the bottom of the script by selecting the 'test_onEdit' function. You could also edit any cell in the appropriate column (in my case, it was the 'Points' column line 61) and that should trigger the function to run.
