I have adapted the create content code to create content for multiple languages at once but I am getting a nullReferenceException: (sorry about the formatting) Can anyone point me in the right direction?

Line 100:        if (!Page.IsValid)
Line 101:            return;
Line 102:        BasePage.Current.ClientTools.ChangeContentFrameUrl(dialogHandler_temp.Create(helper.Request("nodeType"),
Line 103:                                                                                     int.Parse(nodeType.SelectedValue),
Line 104:                                                                                     int.Parse(Request["nodeID"]),
