I am having issues with jquery dialog.  It works using FireFox but not IE 11.  The error message is:

The value of the property '$' is null or undefined, not a Function object

The script and code is:

< script src ="Scripts/jquery-2.1.4.min.js"></ script >

< script src ="Scripts/jquery-ui-1.11.3.js"></ script >

                $("#divAssignPopUp").dialog({
                    autoOpen: true,
                    width: 600,
                    height: 500,
                    resizable: false,
                    draggable: true,
                    closeOnEscape: true,
                    modal: true,
                    show: {
                        effect: "fade",
                        duration: 1000
                    },
                    hide: {
                        effect: "fade",
                        duration: 1000
                    }
                });
