Thanks for letting me know I'm not alone Anne,
I'm still hunting for an answer. I know this can't be so difficult!!! What
am I missing here? HELP!!
Anne, is your database set up with all the "events" in one table, and all the
Filing numbers in another table? Is the link between the two, the filing
number?
Is the field named EventDate? Because if each of the events have a different
name, I would think you could use the following module: Just cut and paste
into a new module, name it something other than Diff2Dates, then use it like
you would any other function. i.e. Diff2Dates("dhn",[Date1],[Date2],0)
It works GREAT!!!

'Description: This function calculates the number of years,
' months, days, hours, minutes and seconds between
' two dates, as elapsed time.
'
'Inputs: Interval: Intervals to be displayed (a string)
' Date1: The lower date (see below)
' Date2: The higher date (see below)
' ShowZero: Boolean to select showing zero elements
'
'Outputs: On error: Null
' On no error: Variant containing the number of years,
' months, days, hours, minutes & seconds between
' the two dates, depending on the display interval
' selected.
' If Date1 is greater than Date2, the result will
' be a negative value.
' The function compensates for the lack of any intervals
' not listed. For example, if Interval lists "m", but
' not "y", the function adds the value of the year
' component to the month component.
' If ShowZero is True, and an output element is zero, it
' is displayed. However, if ShowZero is False or
' omitted, no zero-value elements are displayed.
' For example, with ShowZero = False, Interval = "ym",
' elements = 0 & 1 respectively, the output string
' will be "1 month" - not "0 years 1 month".

Connie, I know exactly what you're trying to get. I'm having the same
problem also. I have multiple events for one filing number (ie received,
letter sent, resubmitted, sent to legal, received from legal, closed) and
each of these events has a date to it. The dates are typically more than one
day apart, so a -1 datediff doesn't help. But I know there "has" to be a way
of counting the days between each event.
Surely someone out there can give us a glimmer of hope!
HELP! This ended up NOT working. I still can't get the difference between
two (or more) ActionDates.
