title: How do I add multiple conditions to "ng-disabled"?
body: <p>I need to check that two conditions are <strong>both</strong> true before enabling a button:</p>
  
  <p>Here is an example:</p>
  
  <pre><code>&lt;button type="submit" ng-disabled="frmUser.pw2.$error.pwMatch" class="btn btn-primary" ng-click="ChangePassword()"&gt;Change&lt;/button&gt;
  </code></pre>
  
  <p>This example only contains one condition within <code>ng-disabled</code>.  How would I add another such as a scope variable?</p>
