COUNTIF or IF Statement

Richard@2018

I am looking to add date columns that are based on a criteria in another cell.  I can use the COUNTIF statement to add the dates but when I place an criteria in place I get an error.  

=COUNTIF([Due Date]:[Due Date], <=TODAY())

This works to count my dates that are less then or equal today but I need it also to filter out if the [Complete Date] ISBLANK to determine correct cell count.  I tried the below form.  but get error out.  

=IF(ISBLANK([Complete Date]:[Complete Date]), COUNTIF([Due Date]:[Due Date], <=TODAY()), "0")

Hopefully someone can point me in the right direction.

Hi Richard,

Try this:

=COUNTIFS([Completion Date]:[Completion Date], ISBLANK(@cell), [Due Date]:[Due Date], <=TODAY())

This will count all cells that both have a blank completion date and have a due date of greater than or equal to the current date. 

Let me know if that's not what you're looking for and I'll be happy to further advise.

Thank you very much this worked perfectly.

Hi, Shaine,

Using your example above, I'm wondering why this is coming up unparseable for me. I'm looking to count in a Summary Field all rows where Student Tasks Completed (date) is either blank or before today (actually I need it to calc and count fields that have dates on or before 7 days before today):

=COUNTIFS([Student Tasks Completed]:[Student Tasks Completed], ISBLANK(@cell)), ([Student Tasks Completed]:[Student Tasks Completed], < TODAY())
