javascript - angular js Formvalidationの解析エラー

Question

こんにちは皆さん、私は新しいAngular jsです。formvalidationを適用していますが、エラーが発生しています

<form  name="myForm" ng-controller='formCtrl'>
    {{message}}
    <div class="form-group">    
          <input type="text" class="form-control" name='propname'  ng-model='propname' placeholder="Property No. or Name *" required>
            <span ng-show="myForm.propname.$dirty && myForm.propname.$error.required">Required!</span>
    </div>
    <div class="form-group">
         <input type="text" class="form-control" id="" placeholder="Flat No. (if applicable)">
    </div>
    <div class="form-group">
        <input type="text" class="form-control" id="" placeholder="Street Name *">
    </div>
    <div class="form-group">
         <input type="text" class="form-control" id="" placeholder="Search Full Postcode *">
    </div>
    <button type="submit" class="btn btn-info">Search</button>
    <span class="floatRight">* Required fields</span>
</form>

ページをロードすると、コンソールにエラーが表示されます
