Good morning,
I'm currently building a flow which triggers off an email message when specific columns of a Sharepoint list are updated.
As part of the criteria, I do not want to trigger this message off when the item is created or deleted - I believe I've covered this issue properly by using this condition:

I now have a column called Grade, which is a choice column. I do not want to trigger the workflow when this column is changed - I think I've got a bit confused with my logic so looking for assistance.
In short the workflow needs the following conditions to work in unison:
If the Item is Created or Deleted - do not complete workflow
If the column Grade is modified - do not complete workflow
