The results page by default just has a heading of Product List. The way the info on the page loads differs from the previous versions.
If you would like to add in the category name you would need to add in an additional recordset that will select from the category table where the id matches the URL param for category id.
You could then use the bindings from this rs to show the category name, and if there is no category specified you could show the Product List default text. Please post back with any questions that you have about any part of this.
