Having trouble with IF and ISBLANK formula

I need help using the ISBLANK formula. I want to return a value of average months between two dates the Closing Date and Reported Date. But when there is no Closing Date I want the system to use the TODAY function and then calculate. But when I try to add in the ISBLANK function I keep getting a syntax error so I know I'm close but missing something.

Here is my simple formula =([Closing Date]@row - [Reported Date]@row) / 30

Here is what I was trying to use but get syntax errors: =IF(ISBLANK([Closing Date]@row), TODAY,[[Closing Date]@row - [Reported Date]@row) / 30]

Hey @Scott Peloquin,

Use ISDATE instead of ISBLANK.

=IF(ISDATE([Closing Date]@row), ([Closing Date]@row - [Reported Date]@row) / 30, (TODAY() - [Reported Date]@row) / 30)
