Popup not showing multiple entries

[AjayGoel1]

I am using Uniquevalue rendered to show different icons with a popup showing details.  For some reason when there are 2 entries in the same lat long, the popup only shows the last entry instead of showing 1 of 2.  I must be doing something silly. 

Attaching the entire code and adding the JS code.

Thanks

dojo.require("esri.map");
dojo.require("esri.layers.FeatureLayer");

dojo.require("dijit.layout.BorderContainer");

var map = null;
var featureLayer = null;

     'marginLeft': '20',
     'marginTop': '20'
   };

 var popup = new esri.dijit.Popup(popupOptions, dojo.create("div"));
   
 map = new esri.Map("map", {
