If "Employee manual entry" column is blank, then I want to do a vlookup to another sheet in the "Employee". If there's text in the "Employee manual entry" column then I want that text to display in the "Employee" column. The formula I'm using is below, but I get an #INCORRECT ARGUMENT SET
Any advice on how to correct this formula?
=IF(ISBLANK([Employee manual entry]@row, IFERROR(VLOOKUP([Created By]@row, {Reference Sheet - Admin Info Range}, 2, false), ""), [Employee manual entry]@row))
Created By is an email address (Smartsheet helper column).
Reference Sheet - Admin Info Range is two column range with emails and then their name.
