Hello @Mira_Ghaly Thanks for your response.
"Just to understand you a bit more , does the run script populate this field?"
Yes, the office script populate this "id" field.
This screenshot show the XLOOKUP I used to the column F (email) data

And this screenshot show the formula I used to get data in Column G (id).

Also you stated that
"I believe you need to yes the Key Column as the eeid because the id is not yet there on the and you are trying to reference it from the Add Row Action"
I think you're right on this one, probably that's why it is returning null data when I reference it. I have to research a little bit more on how to "yes' the key column or confirm this data. Do I need to "yes" the key value too ?
