Hi @Sahara22 ,
Is Homebase the name of your SP list?
I have done a test on my side, using formula like you, everything works fine.


So I would suggest you to check below things:
1. Pay attention to the Formula separators in your region. See my above example, in my region, I use comma, but in the formula you provided, I see both comma and semi-colon.

2. What is the column type of your "Item" column? In my above example, my “Item”,”WhoScnned” and “Time” columns are all Text Column.
So pay attention to the column type of your “Item”,”WhoScnned” and “Time” columns in your SP.
Best regards,
Allen
