Hi, I have an esri sample code attached -- I successfully inserted my basemap but when I tried to add my mapservice, it doesn't error out but it doesn't show the mapservice. Any suggestions on what I'm missing in the code?  Thank you.

When adding code, use the "Insert/Edit code sample" button instead of adding it as an attachment.

The first thing I see is that the require modules don't match up with the function arguments

require(["esri/map", "esri/toolbars/draw", "dojo/promise/all",
    "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", "esri/symbols/SimpleFillSymbol",
    "esri/symbols/PictureFillSymbol", "esri/symbols/CartographicLineSymbol", "esri/layers/FeatureLayer",
    "esri/graphic", "esri/tasks/query", "esri/tasks/QueryTask", "esri/InfoTemplate",
    "esri/Color", "dojo/dom", "dojo/on", "dojo/parser", "dijit/layout/BorderContainer", "dijit/layout/ContentPane",
    "dijit/layout/AccordionContainer", "dojo/domReady!"], function (
Map, Draw, All,
SimpleMarkerSymbol, SimpleLineSymbol, SimpleFillSymbol,
PictureFillSymbol, CartographicLineSymbol, FeatureLayer,
Graphic, Query, QueryTask, InfoTemplate,
Color, dom, on, parser, ArcGISDynamicMapServiceLayer) {

You haven't included the module for ArcGISDynamicMapServiceLayer.

Ken, thank you for the information. I made the modification fine but it's erroring out on something else so I started from beginning.  (Sorry, I'm new to this and I don't see an option to use the "Insert/Edit code sample" button so I will paste it here.)  This is the original esri sample code and I added my basemap fine. But when I add my annexation map service, it doesn't display. Thank you for any suggestions you can provide.

Thank you for the information. I made the modification and then it errored out on something else. So I started from beginning modifying the original esri sample code which I attached initially. (Sorry, I'm new to this and I don't see an option to  use the "Insert/Edit code sample" button so I'm pasting it here.)  The basemap is good but the annexation map service is not displaying. Any suggestion is appreciated. Thank you.

map = new Map("mapDiv", {
// basemap: "streets",
center: [-85.82966, 33.666494],
zoom: 7
});
var baseMapLayer = new esri.layers.ArcGISTiledMapServiceLayer("https://gismaps/arcgis/rest/services/Basemap/StreetBaseMap/MapServer");
map.addLayer(baseMapLayer);

map.on("load", initToolbar);


var featureLayer1 = new FeatureLayer("https://gismaps/arcgis/rest/services/CountyServices/Annexations/MapServer/0", {
mode: FeatureLayer.MODE_SELECTION,
infoTemplate: new InfoTemplate("Case Name: ${CaseName}", "${*}"),
outFields: ["NumParcels"]
});

map.addLayers([featureLayer1, featureLayer2, featureLayer3]);
