I have two lists.
List 1 is the control list containing: Apple, Orange, Lemon, Tangerine, and Grape. List 2 contains Apple, Tangerine, Grape, and Banana.
I need a script that compares the two lists and will eliminate banana from list 2 because banana is not in the control List 1. The script will not add Orange to List 2 even tho it is in the Control List 1.
Perhaps the script would create list 3 with the results (Apple, Tangerine, and Grape)?
Thanks
