Here is the code I am working with:

$(document).ready(function () {

    var TemplateEditor = function () {

        var GroupClassName = 'group';
        var SelectedGroup = 0;

        var BindClicks = function () {
            $('.CriteriaSelections').unbind('click').click(function (event) {
                event.preventDefault();
                if (fnIsTheClickedBoxaGroup($(this))) {
                    TemplateEditor.GroupClicked();
                }
                else {
                    TemplateEditor.CriteriaClicked($(this), SelectedGroup);
                }
            });

            $('.groupselected').unbind('click').click(function (event) {
                event.preventDefault();
                SelectedGroup = $(this).attr('group-'.length);
                TemplateEditor.SelectGroup(SelectedGroup);
            });
        }


        var fnGetGroupID = function (Obj) {
            if (fnIsTheClickedBoxaGroup(Obj) == true) {
                return null;
            }
            else {
                //Get parent which is the group
                var ObjParent = Obj.parent();
                var GID = ObjParent.attr('id').substr('group-'.length);
                return GID;
            }
        }

        var fnIsTheClickedBoxaGroup = function (Obj) {
            var GetClass = Obj.attr('class');
            if (GetClass == GroupClassName) {
                return true;
            }
            else {
                return false;
            }
        }

        return {
            Init: function () {
                BindClicks();
            },
            CriteriaClicked: function (Obj, GroupID) {
                $('<div>').attr({ id: '' }).addClass('selection').text(Obj).appendTo('#group-' + GroupID);
            },
            GroupClicked: function () {

            },
            SelectGroupClicked: function () {

            },
            UpdateTargetPanel: function () {

            }
        };
    } ();
    TemplateEditor.Init();
});

I am trying to access this variable: GroupClassName

This variable is inside this function

var fnIsTheClickedBoxaGroup = function (Obj) {
                var GetClass = Obj.attr('class');
                if (GetClass == GroupClassName) {
                    return true;
                }
                else {
                    return false;
                }
            }

When I run the program it says GroupClassName is undefined. Am I missing something here?
