How do I update my function syntax to stop getting the #INVALID DATA TYPE error?

Tina Gigioli

I'm working within a sheet and trying to calculate the number of days between two dates.

Above is a picture of what I'm seeing and my syntax is below.

=NETWORKDAYS([Start Date]@row, [Date Completed]@row)

I've tried to add IFERROR in a couple places and it didn't help with anything unfortunately. My Task Duration is set as a Number/Text. I've also tried setting it to 'Date' to see if that made any difference, but no luck unfortunately.

Any guidance or direction could be greatly appreciated.

Thanks!

@Tina Gigioli It looks like your Start Date is not a true date value (the year shows as YYYY, while the other dates are in default Smartsheet format of YY.) Make sure that both date columns you are referencing are set to Date-type and that the values in them are actual date values that Smartsheet recognizes.
