    force fields (2000)

    Hello, have a combo where if a certain value is selected I then need to have a second field (a date field) forced so that the user has to enter a date. How can I code this in VBA? So if combo is called received and if value 1 is selected I then need to have field 'date' forced before user can move on.

    You can set focus to the date text box in the After Update event of the combo box.
    You can check whether a date has been entered in the Before Update event of the date text box. (I wouldn't actually call it 'date' since that is a built-in function)

    With a combo box named cmbReceived and a text box named txtDate:

    Private Sub cmbReceived_AfterUpdate
    ' Did the user select 1?
    If Me.cmbReceived = 1 Then
    ' If so, set focus to the date text box.
    End If
    End Sub

    Private Sub txtDate_BeforeUpdate(Cancel As Integer)
    ' Did the user select 1 in the combo box and leave the date blank?
    If Me.cmbReceived = 1 And IsNull(Me.txtDate) Then
    ' If so, issue a warning ...
    MsgBox "You MUST enter a date!", vbInformation
    ' ... and cancel the update.
    Cancel = True
    End If
    End Sub
