Formula for Flagging Repetitive Values

Copper Contributor

Hi Everyone

 

I was hoping for some advice.

 

Ive simlified my request below with a simple table.

 

I want to flag in column A with the use of a formula if a value repeats somewhere in Column B

 

So for example below Error Code 1, Error Code 6 appear more than once in Column B  So i want to flag it.

 

Ive used the term repeat 🙂

 

Goal
