Changing constants in a query to user input values

I have a table that contains (among other things)
Start Date
TimeDown
End Date
TimeUp

All of these are Date/Time type

Example data:

Start Date TimeDown End Date TimeUp
16/3/10 02:00 16/3/10 04:00
16/3/10 06:00 16/3/10 09:00
16/3/10 19:00 16/3/10 20:30
16/3/10 23:00 17/3/10 01:00
17/3/10 03:00 17/3/10 04:00
17/3/10 08:45 17/3/10 09:30

I need to be able to return only those Start Date & Time Values that occur
between 5pm on the first date and 5am on the second date. In the above
example data, this would be the 3rd, 4th and 5th lines. This is for a report
that covers Night shift.

I have a select query with constants:
Field:
NightShift: [Start Date]+[TimeDown]
Criteria:
Between #16/03/2010 5:00:00 PM# And #17/03/2010 5:00:00 AM#

and this seems to work.

What I need to be able to do is have a user input a date range (using a form
for Start Date and End Date - which I can do) but have only the time frame
5pm on the Start Date to 5am on the End Date.

I would really appreciate any assistance as I'm still muddling my way
through...

TIA

If I understand correctly, you want something like

Between DateAdd("h",17,[Forms]![FormName]![StartDate]) and
DateAdd("h",5,[Forms]![FormName]![EndDate])

Since that would only work for a one day range you could use

Between DateAdd("h",17,[Forms]![FormName]![StartDate]) and
DateAdd("h",29,[Forms]![FormName]![StartDate])

If you wanted multiple days you would need something more complex.
Criteria Under [Start Date]
Between [Forms]![FormName]![StartDate] and [Forms]![FormName]![EndDate]

Criteria under TimeDown
(TimeDown <= #05:00:00# OR TimeDown >=#19:00:00#)

Alternative criteria for TimeDown
NOT BETWEEN #05:00:01# and #16:59:59#

Thank you John.

Between DateAdd("h",17,[Forms]![FormName]![StartDate]) and
DateAdd("h",29,[Forms]![FormName]![StartDate])

works perfectly for what I'm doing!

You guys who answer these questions are Legends!
