Modules and Forms

[James T.]

Using Access 2000

After doing a little research I found the following Module
and have copied it to try and learn how forms relate to
modules. I would like to have a form where the user inputs
a DATE (04/11/05), a TIME(8:16AM) as a start time and also
enter a finish time (04/13/05 3:00PM) and have Access
calculate the days and hours between the two. I am looking
to understand how this module might help me. The text
within the link states "type such and such (dates and
time) into the Immeadiate window. Don't know what
the "Immeadiate window" is :-(

Any help or links appreciated.

Thanks,
James

' The function accepts interval arguments such as the
following:

' #5/12/95 6:00:00AM# - #5/11/95 10:00:00PM#
