VBA issue

Thank you for your message Daniel_Pineault!

1. Yes, code is compiling w/o errors; here it is:

Private Sub Form_BeforeUpdate(Cancel As Integer)
'***********************************************
Dim EmbTimeZone, DestTimeZone As Variant
Dim ETZ, DTZ, FlightMins, FlightH, FlightM As Integer

On Error GoTo err_point
Stop
If Not Me.NewRecord And Me!Embarkment = Me!Embarkment.OldValue And Me!Destination = Me!Destination.OldValue And Me!TakeOffLocDateTime = Me!TakeOffLocDateTime.OldValue And Me!LandingLocDateTime = Me!LandingLocDateTime.OldValue Then GoTo exit_point
EmbTimeZone = DLookup("TimeZone", "CITIES", "x=" & DLookup("City", "AIRPORTS", "Embarkment=" & Me!Embarkment))
ETZ = CInt(EmbTimeZone)
DestTimeZone = DLookup("TimeZone", "CITIES", "x=" & DLookup("City", "AIRPORTS", "Destination=" & Me!Destination))
DTZ = CInt(DestTimeZone)
FlightH = IIf(ETZ * DTZ < 0, Abs(DTZ) + Abs(ETZ), Abs(DTZ - ETZ))
FlightMins = Abs(CInt(DateDiff("n", Me!LandingLocDateTime, Me!TakeOffLocDateTime))) + FlightH * 60
If FlightMins <= 0 Then
Cancel = True
Beep
MsgBox " ... and, instead, it is " & FlightMins & " minutes!", vbCritical, "Wrong data rejected: flight time should be strictly positive..."
Else
FlightH = FlightMins / 60
FlightM = FlightMins Mod 60
Me![FlightTime] = FlightH & ":" & FlightM
End If
exit_point:
Exit Sub
err_point:
Cancel = True
MsgBox Err.Source & " -> " & Err.Description, vbCritical, "Error in method Form_BeforeUpdate of module OPTIONS..."
End Sub

2. No I did not repair Office: I do not think it needs, all other applications are working fine. Moreover, very complex Access applications that I developed in years under previous US Access versions are working fine even under this Romanian one as well.

3. Being a subscription, I always have the latest version that is updated automatically immediately after such updates are available. Currently, it is compilation 130001.20384 of the 2006 version.

Moreover, before contacting Microsoft, I tried one of the "solutions" circulating on the net, namely to change the international settings of Windows to Romania (instead of US), but in vain, the VBA code is not running either and Access is issuing the same error message.

Thank you once more for your time and kindness,
