Hi, I have a category list web part and a repeater web part at the same page. When a category in the list has been clicked, it will add this specific categoryid querystring in the URL. The repeater will capture it and list all the blog entries under this specific category.

It works perfect on this case. I would like to show the category name in the repeater. I can show the category id via put in {%categoryid%} in Content Before inside the HTML envelope of the repeater. But how can I retrieve and show the category name by this category id?
