## IF ISBLANK Return Blank

Hi guys, Basically, if Date2 is blank then Age column should be blank because there is nothing to compare to.

`DaysBetweenDates = IF(ISBLANK([Date1),BLANK(),([Date2] - [Date1)*1.)`

I'm struggling correcting this formula

`Column = IF(ISBLANK('Table1'[DaysBetweenDates]),BLANK(),IF(''Table1'[DaysBetweenDates]< 46,"< 45 Days","45+ Days"))`

Thanks

I think you need to check both for blank before you make the calculation here:

`DaysBetweenDates = IF(ISBLANK([Date2]),BLANK(),if(ISBLANK([Date1]),BLANK(),([Date2] - [Date1)*1.))`

Then your 2nd one would work.

Hi @Stuznet

Shouldn't your first formula be the one below?

`DaysBetweenDates = IF(ISBLANK([Date2),BLANK(),([Date2] - [Date1)*1.)`  Helper V

Hi @gooranga1 the second formula is the one I'm looking for  Impactful Individual

I can't see your data but the second formula is reliant on the first. Are you 100% sure the first formula is returning Blank()?

From your sample data the first formula may not return blank as Date1 is never blank and the so the 2nd part of the first formula will always execute which is Date2 - Date1?

Maybe add DaysBetweenDates to your table so you can see what this is actually returning as it clearly it isn't returning Blank().  Helper V It is calculating something eventhough Date2 is blank  Resolver II
