Get data from one list to another

 Hi ganeshsanap ! 

Thanks for your help. 

So my Sharepoint is in French, I'll try my best to translate appropriately.

I'll enclose some screenshots as well. 

My power automate flow right now is:

1- When an item is created or modified (pic enclosed; capture 1)

>With the address of the sharepoint and the name of the contact list

2-Get item (capture2)

>With the address of the sharepoint (same for both lists) and the name of the region list. And the ID from "when an item is created or modified"

3-Update item (capture 3 & 4)

>With the address of the sharepoint, the name of the contact list, the ID from "Get item"

>and in the column where I want the salesman name; the link to the person column from the region list. 

There are several choices (I guess because it's a person column so it can get all the company's info), I chose the one that doesn't have any word attached to it (last one). I guess I could also choose DisplayName, but that doesn't solve my problem...

When I save it, I get a warning that I may get an infinite loop. 

And when I test it, I don't get any salesman name. 

Thanks for your help!
