title: Alexa Skill not recognized when tested on Echo
body: <p>I was doing one of the tutorials (HelloWorld) to make a skill for the Echo and I followed the directions. When I tested the skill using the Service Simulator, I typed in </p>
  
  <pre><code>Alexa, tell Greeter to say hello
  </code></pre>
  
  <p>and that returned the following JSON response:</p>
  
  <pre><code>{
    "version": "1.0",
    "response": {
      "outputSpeech": {
        "type": "PlainText",
        "text": "Hello World!"
  },
  "card": {
    "content": "Hello World!",
    "title": "Greeter",
    "type": "Simple"
  },
  "shouldEndSession": true
    },
    "sessionAttributes": {}
  }
  </code></pre>
  
  <p>I think that is the correct output. However, when I tried testing the skill on my Echo, Alexa replies "Sorry, I didn't your question." I went on the history and Alexa interpreted my command as "alexa tell greeter to say hello." It seems that Alexa is not recognizing the skill? </p>
  
  <p>I am using Amazon Lambda to execute the code, so I checked the logs and the code was not executed when I spoke the command to above. </p>
  
  <p>I replaced the app_id in the javascript file to the one that corresponds to my skill. I have also put the amazon skills kit as a trigger. </p>
  
  <p>I also tried the other tutorials (ChemistryFlashCards and HistoryBuff), and Alexa replies "I'm not sure what you meant by that." </p>
  
  <p>Not sure what is happening! Any guidance is appreciated!!</p>
