Trying to add arcgis online layer to map

jaykapalczynski

From examples I am trying to add this to the code below:

  
arcgisUtils.createMap("7f843bb0a37849f68a5a2cc3d2b06288", "mapDiv").then(function (response) {
        map = response.map; 
});

Nothing shows up...its sort of a combination of two examples....just want to add data from a WebMap and from a REST enpoint...anyone know what I am doing wrong?

var map, tb;

      require([
        "esri/map", "esri/toolbars/draw", "esri/arcgis/utils",
        "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol",
        "esri/symbols/PictureFillSymbol", "esri/symbols/CartographicLineSymbol", 
        "esri/graphic", 
        "dojo/_base/Color", "dojo/dom", "dojo/on", "dojo/domReady!"
      ], function(
        Map, Draw, arcgisUtils,
        SimpleMarkerSymbol, SimpleLineSymbol,
        PictureFillSymbol, CartographicLineSymbol, 
        Graphic, Color, dom, on
      ) {
  
  arcgisUtils.createMap("7f843bb0a37849f68a5a2cc3d2b06288", "mapDiv").then(function (response) {
        map = response.map; 
  });
    
 map = new Map("mapDiv", {
          basemap: "topo",
          center: [-77.4329, 37.5410],
          zoom: 7,
          slider: true   
        });
        map.on("load", initToolbar);

Remove this:

          
    map = new Map("mapDiv", {
          basemap: "topo",
          center: [-77.4329, 37.5410],
          zoom: 7,
          slider: true      
        });

You are already creating your map using response.map 😃

After removing this code, I see your webmap and what appear to be streams/rivers, colored with purple.
