Hi rcwatson.
That code doesn’t create a new sidebar, it displays a sidebar that has already been created. The normal way wordpress creates sidebars does not apply to Widget Wrangler
I highly recommend watching the screencasts on the Widget Wrangler plugin page to get started. The first one will walk you through creating a new sidebar and placing the code into your template file.

Basic Examples w/ Advanced Parsing Screencast
Templating & PHP
Generally, here are the steps:
1) Install Widget Wrangler and you’ll see a new Widget Wrangler Menu in your admin interface.
2) In that new Widget Wrangler menu on the left in the admin interface, click on Sidebars. This is where you’ll create new sidebars. Type the name of your new sidebar into the ‘Create Sidebar’ area of this page and click Create.
3) Once the page refreshes, you’ll should see the sidebar you created and it will show the sidebar slug you need to put into the ww_dynamic_sidebar function in your template.
