Date math again...

[Butch Ammon]

Good afternoon,

I have another question regarding dates, calculations, and taking into account 
weekend dates.  Isn't there a simple way of doing this?

Example:

  If:
Then: dd = (10 - 9)
  If:
Then: Show "@This is the total number of days " < dd
  If:
Then: end

  Field 9 is the date when the order was entered (i.e.. 12/06/05)
 Field 10 is the date when the order was shipped (i.e.. 12/21/05)

Dummy field "dd" comes up saying 15 for the total number of days, which is 
correct.  **BUT** what about weekends?  It counted Dec 10th, 11th, and also Dec 
17th and 18th as work days!  Technically, dummy field "dd" should be: 11 days.

My main question:  Does anyone have a quick and easy method of doing date math 
and taking into consideration the weekends inbetween the two dates?

Thank you very much for your help!
