If you have properly created your Add-On domain in your Control Panel according to the Tutorials, and your page is "freestyles" then the link to that page looks like:
http://www.streetarena.tv/freestyles,html
To PUBLISH that page, you will need to change the Publish Dialog Box to look like this:
public_html/streetarena
(and according to which type of cPanel you have, sometimes you may need to add the .com to look like this:
public_html/streetarena.com)
So .... if you created your Add-On properly, Saved your Page properly as "freestyles" and then Published properly, the page should in fact be there
