Hi !
I have a table with 2 columns that must be unique.
The instagram name must be unique so I put the formula:
=NOT(IN([_THIS], app_bloggeuses[insta_name]))
It works perfectly, the only problem is that is when I want to edtit, I can not save.
I tried to in Editable_if:
=[_THIS]=""
It does the same.
How could I solve this?
