I am trying to do the following but doesn’t seem to work.

```auto
<ActivatingAnimation>
  <iOS>
      <Change second_rgt_btn.Opacity="1"/>
  </iOS></ActivatingAnimation>

```

Hi!

In your code you have a [Trigger](https://www.fusetools.com/learn/fuse#trigger-triggers-and-animators) inside another trigger, (`<iOS />` inside `<ActivatingAnimation />`). So what will happen is when `<ActivatingAnimation />` triggers it will add `<iOS />` to its parent.

To achieve the desired behavior, try writing it like this:

```auto
<iOS>
    <ActivatingAnimation>
        <Change second_rgt_btn.Opacity="1"/>
    </ActivatingAnimation>
</iOS>

```
