Counting Blank Fields

[BrickMad]

I have a field with the time of day in it, however I want to count this field when the time of day has not been added , any ideas?

Thanks

Perform a record count (like on the PK) and a count on the specific time of day field.
The difference should be the number of empty fields..

Or a calculation like TOTAL(CASE WHEN (TIME_FIELD = "" OR TIME_FIELD is NULL) THEN (1) ELSE (0) END)).
