I am having problems adding a block to my sidebar in one of my category pages.
I am using the Custom Layout Update function to add my bestsellers to one specific category page. 
The XML file for my bestsellers is created and the code inside is that one

```
    <reference name="left">
        <block type="bestsellers/view" name="bestsellers.sidebar" before="-" template="bestsellers/view.phtml"/>
    </reference>

```

and then in the Category I have added this 

```
 <reference name="left">
    <block type="bestsellers/view" name="bestsellers.sidebar" before="-" template="bestsellers/view.phtml"/>
    <remove name="catalog.leftnav"/>
 </reference>

```

but still it´s nothing showing up there. I am confused why this won´t work. I also thought of adding the block to a static cms block but this won´t work either.

Any suggestions?
