Hi @Tom_Maskell ,
Welcome to Make Community!
It seems everything has been set up properly. For your information, you don’t need to select any sheet or make additional selections in Make. You just need to add the webhook to the Google Sheet, and that’s it. It should trigger the scenario when you change the specified column, so it should work as expected.
Also, you can create a custom webhook and try integrating it instead of using the native Google Sheets “Watch: changes” module. In this way, you can trouble shoot his issue.
