I am having some issues showing a div that i am hiding. For some reason the #ElementId selector isnt working but if i just use ElementId it works.

Jquery 1.7.1 also I am using JQuery ui.

```
$('CreateGroup').show("fold"); // this works fine
$('#CreateGroup').show("fold"); // this fails with cannot call show on undefined

 <div id="CreateGroup" style="display: none">Hi!</div>

```

What's going on?

Thanks
