rss not working

Hi,

I'd like to ad a specific blog to my mailchimp normal newsletter. I started to put in my whole blog. But i dont get that working.

I have put in

*[FEED: http://www.skyb-administraties.nl/index.php/blog/latest?format=feed&type=rss}*

I get the message: RSS not found

What do i do wrong? And how do I get 1 blog item posted?

I dont want to have the blog menu visible on my website. So it is hidden.

Hope to hear from you soon.

With kind regards,
