Access 2000 Calculations

[OCM]

Greetings,
I have two combo boxes AppStatus (with drop down NEW, REDETERM etc) & EligStatus (with drop down ELIG, DENIED etc) depending on what the user selects from each field, EligDays = the difference between two fields.

I'm new for programming. How do I get the result, (work days) not counting weekends, automatically to be filled in EligDays field?

Thanks,

DD


The following is the code i have please comment:

Private Sub AppStatus_AfterUpdate()

If [AppStatus].Value = "NEW" And [EligStatus].Value = "ELIG" Then
EligDays.Value = DateDiff("d", [AppRec], [EligDate])


ElseIf [AppStatus].Value = "NEW" And [EligStatus].Value = "DENIED" Then
EligDays.Value = DateDiff("d", [AppRec], [EligDate])


ElseIf [AppStatus].Value = "NEW" And [EligStatus].Value = "REACTIVATE" Then
EligDays.Value = DateDiff("d", [Reassess], [EligDate])


ElseIf [AppStatus].Value = "REDETERM" And [EligStatus].Value = "ELIG" Then
EligDays.Value = DateDiff("d", [RedetDue], [EligDate])


ElseIf [AppStatus].Value = "REDETERM" And [EligStatus].Value = "DENIED" Then
EligDays.Value = DateDiff("d", [RedetDue], [EligDate])



ElseIf [AppStatus].Value = "REDETERM" And [EligStatus].Value = "REACTIVATE"
Then
EligDays.Value = DateDiff("d", [Reassess], [EligDate])

Else
EligDays.Value = Null

End If


End Sub
