Thank You so much for your answer. I tried to put
$model.weblog.getWeblogCategory("/Noticias") and i still get the same
problem.
Also i tried with:

- #showWeblogCategoryLinksList("/Noticias" false true)
- $model.weblogCategory("/Noticias")
- This code from de roller template guide

#foreach ($cat in $model.weblog.categories)

#if ($cat.name != "Music")

$cat.name<br>

#end

#end

I tried several ways using the roller- template guide. And i can't find
something that helps. Is there a macro that just display a string that i
tell it to. Something that works like an echo on other languajes? I just
want to get the name of the category and display it.
