Add block to sidebar doesn´t work

Question

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?

Answer 1

For particular category , you can manage it from admin too.From Manage Categories > Your Category > Custom Design > Custom Layout Update

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

Answer 2

This is correct

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

The issue was that I wanted this on my frontpage but it didnt work because the Bestsellers from the root catalog wouldn´t work so after putting it into a category page it worked fine.
