I am trying to use HTML to:

* Create 2 Ordered Lists
* Within Each of the O.L. nest a Unordered List and add some elements inside

However, my numbering isn't working the way it should, I'm getting, *1. 1.* rather than *1. 2. etc.*

My code:

```html
<ol>
  <li>Fruits</li>
  <ul>
    <li>Apples</li>
    <li>Oranges</li>
    <li>Plum</li>
    <li>Watermelon</li>
  </ul>
</ol> 
<ol>
  <li>Vegetables</li>
  <ul>
    <li>Carrots</li>
    <li>Lettuce</li>
    <li>Cucumber</li>
    <li>Tomato</li>
  </ul>
</ol>
```
