I'm trying to use `Fullpage.js`. Here is my script:

```
<div id="fullpage" style="margin-top: 55px">
    <div class="section" id="first" style="background-color: red">Some section - Home</div>
    <div class="section" id="services" style="background-color: blue">Some section - Services</div>
    <div class="section" id="why" style="background-color: green">Some section - Why</div>
    <div class="section" id="portofolio" style="background-color: red">Some section - Portofolio</div>
    <div class="section" id="price" style="background-color: blue">Some section - Price</div>
</div>

<script type="text/javascript">
   $(document).ready(function() {

$('#fullpage').fullpage({
    menu: '#navbarNav',
    css3: true,
    scrollingSpeed: 1000
});
});
</script>

```

The problem is, there is no slide effect in my HTML page. Any solutions? I don't see any errors in my browser console.

UPDATE

There is a second problem, When I scroll to random section then I click the menu, the anchor is not working, I mean it keeps at the section which I scroll.
