Please enter feedburner URL in valid format

Hi,

I'm trying to ad my blog to a blog directory, the RSS feed for which is:

http://findfranchisepartners.com/blog/?feed=rss2

but I'm getting an error message that says:

"Please enter feedburner URL in valid format."

I entered the above feed in feedvalidator.org and they say it's a good feed.

What gives?

Thanks!
