Hi, All,

I've been trying to interpret me needs from the following thread, but
have not been able to do so. When I tried to apply it to my table and
fields, I'm getting some funky results:
http://groups.google.com/group/microsoft.public.access/browse_thread/thread/aa6566752c5be1eb/a1d50ff9465684ad?hl=en&lnk=gst&q=date+difference+between+two+records#a1d50ff9465684ad

I do need to do something similar. I have a table containing records
of comments associated to my master record using the KeyID. I need to
calculate the working days (using the dhcountworkdaysa calculation
found on the Access Web) between comments to determine if our staff is
contacting customers at least every three days. Where I'm struggling
is with the earliest comment. If it is the first comment, I would
like it to return a zero value since that's that jumping off point
(accept in the case of New records, I want to calculate the difference
between the last status change and the current date).

Any help would be greatly appreciated. I have pasted some sample data
below.

Try this, I know it works since I've been using it for 13 years:

Thanks, Arvin. That does give me an alternative to using the
dhcountworkdaysa function when calculating two dates within the same
records. Where I'm getting stuck, though, is comparing two dates
between consecutive records. Here's what I'm hoping to achieve:

KeyID Date Entered Comment Date Work days since last
comment
1234 1/24/2010 1/24/2010
0 (since it's a new record)
1234 1/24/2010 1/26/2010
2
1234 1/24/2010 1/28/2010
2
12345
5/30/2010 1 (since no
comments were entered, use current date as default)

I hope that helps clarify

The sample above appears to be from the same record, but maybe it difficult
to read with newsreader wrapping.

It is possible to do consecutive records, but it will take some time to
write and debug the code to do it. What you will need to do is to build a
recordset of the records that you want to compare, sorted on the field that
you are comparing on. Now start looping through the recordset and take the
first value, and save it to a variable, then subtract the next row of data,
and update or append the result to a table. Then go to the next row after
saving the previous row to the same variable. Just keep looping until you've
finished.

When you get it (it will take a while to debug) please post it back to this
thread.
