Dynamic Legend Not Working

Hello,
I am very new to javascript and am having trouble with the dynamic legend in my web map. In the content pane on the right it says "No Legend". Any help would be greatly appreciated!!

map = new esri.Map("map",{ nav:true, extent:intExtent, lods: lods});
   var legendLayers = []; 
        //Add the topographic layer to the map. View the ArcGIS Online site for services http://arcgisonline/home/search.html?t=content&f=typekeywords:service     
        var basemapUrl = "http://slcarcgisdev1/SLCOGIS/rest/services/public/Base_Map/MapServer"; 
        var basemap = new esri.layers.ArcGISDynamicMapServiceLayer(basemapUrl); 
         map.addLayer(basemap); 
  
  var layer = "http://slcarcgisdev1/SLCOGIS/rest/services/public/Surveyor/MapServer"; 
        
  
  
  //dynamicMap = new esri.layers.ArcGISDynamicMapServiceLayer(layer);
   esri.config.defaults.geometryService = new esri.tasks.GeometryService
   ("http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"); 
   
   
   var pointsLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://slcarcgisdev1/SLCOGIS/rest/services/public/Surveyor/MapServer",{id:'Control Points'});
  map.addLayer(pointsLayer);
  
  dojo.connect(map,'onLayersAddResult',function(results){
         //add the legend
          var legend = new esri.dijit.Legend({
            map:map,
            layerInfos:[{layer:layer,title:"Legend"}],
            arrangement:esri.dijit.Legend.ALIGN_RIGHT
          },"legendDiv");
          legend.startup();
        });
  map.addLayers([pointsLayer]);
  
  //add check boxes  
        dojo.forEach(legendLayers,function(layer){          
         var layerName = layer.title; 
         var checkBox = new dijit.form.CheckBox({ 
            name: "checkBox" + layer.layer.id, 
            value: layer.layer.id, 
            checked: layer.layer.visible, 
            onChange: function(evt) { 
              var clayer = map.getLayer(this.value); 
              if (clayer.visible) { 
                clayer.hide(); 
              } else { 
                clayer.show(); 
              } 
              this.checked = clayer.visible; 
            } 
          }); 
 
          //add the check box and label to the toc 
          dojo.place(checkBox.domNode,dojo.byId("toggle"),"after"); 
          var checkLabel = dojo.create('label',{'for':checkBox.name, innerHTML:layerName},checkBox.domNode,"after"); 
           dojo.place("<br />",checkLabel,"after"); 
        });

The layer property of a layerInfos object needs to a some kind of JSAPI layer. In your code, it looks like layer is a string. Also, you only need to add your layer to the map once, see my comments in a similar thread from earlier today.
