What exactly are you trying to do? Just put that link in an index php will not really do anything. It can't do anything. If you want to parse the content of a feed in a page, you will need to add some php parser, like carp, inside that index.php
On the other hand, the link you sent me is not correct. There are some blank spaces inside it, that cause the link to be broken. For example "
www.th eautochannel.com" or "
www.volcars.co m"
Before trying to add the content in a site, you should be sure you use correct feeds in rssm and you also get a valid feed back. (loading that link in a browser without getting some error means you have a correct feed)
