Don't allow new record to be added from a form if a command buttin was not clicked

To further explain...  here is my code:

Private Sub cmdAddRec_Click()
On Error GoTo Err_cmdAddRec_Click
   
    If Me.cboToWH = "AT" And Me.chkbxRedButton.DefaultValue = False Then
        MsgBox "Since this is a shipment for Tijuana you must click the red button!"
        Me.chkbxRedButton.SetFocus
    End If
   
   
    DoCmd.RunCommand acCmdSaveRecord

    DoCmd.GoToRecord , , acNewRec
    Me.cboPartN.SetFocus
    Me.txtJobN.TabStop = False
    Me.txtDateEntered.TabStop = False
    Me.txtDateDue.TabStop = False
    Me.txtPOn.TabStop = False
    Me.cboToWH.TabStop = False
    Me.txtCarrier.TabStop = False
    Me.txtProN.TabStop = False
    Me.txtWHlocation = ""
    Me.Command67.Visible = False

Exit_cmdAddRec_Click:
    Exit Sub

Err_cmdAddRec_Click:
    MsgBox Err.Description
    Resume Exit_cmdAddRec_Click
   
End Sub


So, after the "Me.chkbxRedButton.SetFocus" line I want the form to stop and wait for the user to click the command button.  How do I do this?
