Issue with calculating days between two dates - returns #INVALID OPERATION

.Leon.

Hi All,

I have a column Start Date - that is formatted as a DATE column type

Then I have a TENURE column - that is formatted as a TEXT/NUMBER column type

In the TENURE column I am using the formula;

=TODAY() - [Start Date]@row

This formula used to work fine for me - but more recently when I log into the sheet it now returns an invalid operation error on me.

Anything I am doing wrong here?

Thanks!

Hi @.Leon.

I hope you're well and safe!

Strange!

Everything looks correct.

Here's more information about the error.

#INVALID OPERATION

Cause

Operators (see Create and Edit Formulas for details on acceptable operators) in a formula aren't supported in Smartsheet or are mistyped. For example, this IF statement that returns the text "Low Stock" if a cell contains 25 or less...

=IF(Quantity1 =< 25, "Low Stock")

...has the "less than or equal" to operator in the wrong order; the correct order being <= to make the formula =IF(Quantity1 <= 25, "Low Stock")

Resolution

Check all operators to make sure they're not mistyped and are supported by Smartsheet. See Create and Edit Formulas for details on acceptable operators. The most common cause of this is typing <= (less than or equal to) and >= (greater than or equal to) operator combinations in the wrong order.

If you haven't already, I recommend reaching out to the Smartsheet Support Team.

I hope that helps!

Be safe and have a fantastic weekend!

Best,
