I am attempting to use a java script text resize function on a website. But, it is not working. I wonder if any one can spot a coding error that I am not seeing? Thanks!

<http://sample.myblackhairstyle.com/> (resizer is in top right hand corner "Make Text Bigger).

In header.php I put:

```
    <script type="text/javascript">function resizeText(multiplier) {
  if (document.body.style.fontSize == "") {
    document.body.style.fontSize = "1.0em";
  }
  document.body.style.fontSize = parseFloat(document.body.style.fontSize) + (multiplier * 0.2) + "em";
}</script>`

```

Place this where wanted resizer to appear:

Make text bigger | Make text smaller
