I have a list which has a "Person or Group" column called as Reviewer. I want to notify the reviewers whenever he/she is added to the list item.
I created a custom workflow which sends a mail on item creation to reviewers. However, when an item is edited i want that if a person was already there as a reviewer, skip him. If he/she is newly added, send him a mail.
The way I was trying was that, I created a second column named as Reviewer1 and am trying to compare the two columns Reviewer and Reviewer1. If someone exists in Reviewer1 and not in Reviewer, send him a mail. Can someone please help to compare the two columns?
