I have this piece of JS:

```
var count = $(".parent a").length;
$(".parent div").width(function(){
    return ($(".parent").width()/count)-5;
}).css("margin-right","5px");

```

But it doesn't seem to work on my website even though it works fine on [JSFiddle](http://jsfiddle.net/mohsen4887/WeQwc/8/)

I used `"http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"`

But didn't work.

I don't have any other Script on my website as I've just started it.

Is it just a case of using the wrong plug-in?

UPDATE

This is my full code:
