Redirection not working

I’ve just installed Redirection and it’s not working for me. I have a subdomain, dogsdontlookbothways, and my blog is within that (dogsdontlookbothways.com/joeys_blog). I would like one of the pages in the blog to redirect to the blog home page. But it’s not working: I am getting the message ‘sorry but your redirection was not created.”

I am putting in redirect:
http://www.dogsdontlookbothways.com/joeys_blog/index-dog-health-care-emergency/

to: http://www.dogsdontlookbothways.com/joeys_blog/

What’s the problem?
