I am not sure weather I have injected everything right here? Any help would be appreciated. This is my first angular app so I am a little green. Stack Overflow is telling me I have to type more details but the code post are pretty self explanatory. I

Check in index.html if you are importing agencyResource.js before agencyListCtrl.js — emed
I am a bit curios on your agencyResource resource declaration. You are injecting '"ngResource", "$resource", "appSettings"', but your parameters are 'agencyResource($resource, appSettings)'. Could be a broblem. — Vladimir M

The answer is that I was declaring ngResource in the agencyResource.js file. It should look like this. MY BAD.

agencyResource.js

(function () {

    "use strict";

    angular.module("common.services")//common.services
        .factory("agencyResource",
                [
                 "$resource",
                 "appSettings",
                  agencyResource
                ])

    function agencyResource($resource, appSettings) {
        return $resource(appSettings.serverPath + "/api/v1/agencies/:id", null,
            {
                'update': { method: 'PUT' },
            });
    }

}());
