Hi! I need a formula that looks at two columns and returns an email address based on vlookup if one of the two columns is blank and two email addresses (again based on vlookup) if neither column is blank. The formula works well when one of the columns is blank and only one email address is returned. The problem is when two email addresses are returned Smartsheet doesn't recognize either of them as users.
The values are returned to an Assigned to contact list field with multiple contacts checked.
Here's the formula:
=IF(ISBLANK([Position 2]@row) = true, VLOOKUP([Position1 Div]@row, {Copy of Master Phone List Range 1}, 6, false), VLOOKUP([Position1 Div]@row, {Copy of Master Phone List Range 1}, 6, false) + " " + VLOOKUP([Position2 Div]@row, {Copy of Master Phone List Range 1}, 6, false))
