Hello :)
Excelchat Expert 20/11/2017 - 02:30
So you want to highlight only the numbers that aren't 5, 19, and 79?
User 20/11/2017 - 02:31
yes
Excelchat Expert 20/11/2017 - 02:31
Okay, so you would create three different conditional formating formulas.
Excelchat Expert 20/11/2017 - 02:32
Is that how column B is setup?
User 20/11/2017 - 02:32
yes
Excelchat Expert 20/11/2017 - 02:32

Sure. One moment and I will show you how to do this.
Excelchat Expert 20/11/2017 - 02:33
You may only need one formula.
Excelchat Expert 20/11/2017 - 02:40
Looks like you will need 3 separate formulas.
User 20/11/2017 - 02:41
