Nandani's response lacks depth and specificity in addressing the troubleshooting of a script error in Google Sheets. While she mentions using ChatGPT for assistance and analyzing data for errors, she does not demonstrate a clear understanding of the steps involved in diagnosing and fixing script errors. The benchmark response outlines a systematic approach, including reviewing error messages, checking the script editor, and using debugging tools, which Nandani's response does not cover. To improve, Nandani could have detailed specific troubleshooting steps, such as checking for syntax errors or using Logger.log for debugging.
