Sorry to ask but, I really don’t find how to UPDATE an Airtable field with a NULL value. This field contains an initial value I need to remove. I tried using “” , ‘’ , , BLANK(), but nothing works as the updated field contains then “” or ‘’ or space or BLANK() !
Okay, I found a workaround : insert an input text field on the screen, no value, hidden. Then refer to this blank input field to update fields with null value. It works fine.
