Can anyone help with this? I keep getting the #Data Invalid Type message. I am referencing one column to bring back the Month name in another. It works fine where there is a date but when the cell in the Test Start Date column is blank i get the #Data Invalid Type message.
Here is the formula I am trying to use. Like I said works good when there is a date in the column. Both columns are Date columns. I am using parent/children rows, but those also work fine when I put in a fictitious date.
Any help that is good help is appreciated.
Brings back the error with or without the first IF statement.
My formula
=IF(MONTH([Test Start Date]@row) = " ", " ", IF(MONTH([Test Start Date]@row) = 1, "January", IF(MONTH([Test Start Date]@row) = 2, "February", IF(MONTH([Test Start Date]@row) = 3, "March", IF(MONTH([Test Start Date]@row) = 4, "April", IF(MONTH([Test Start Date]@row) = 5, "May", IF(MONTH([Test Start Date]@row) = 6, "June", IF(MONTH([Test Start Date]@row) = 7, "July", IF(MONTH([Test Start Date]@row) = 8, "August", IF(MONTH([Test Start Date]@row) = 9, "September", IF(MONTH([Test Start Date]@row) = 10, "October", IF(MONTH([Test Start Date]@row) = 11, "November", IF(MONTH([Test Start Date]@row) = 12, "December")))))))))))))
