I know Count is supposed to return a count of non-null items. But is there an easy way to return the number of null or empty cells in a column containing dates?

Hi Keith,

You can use an expression like:

= AllValues(Fields.date).Length - Count(Fields.date)

It gets the length of the array of all the values, and subtracts the non-null values, i.e. the result is the number of null entries.
For more information on the functions used in the above expression you can check the Aggregate functions article.
