Can't get it to work

[Ruriko]

I can't seem to get it syndicate from this xml http://safebooru.org/index.php?page=dapi&s=post&q=index&tags=touhou

For testing purpose I wanted to map @id as the post title but it doesn't work. I assume my settings are wrong? here's a screenshot http://i.imgur.com/ypFeIqV.jpg can you tell me how to fix this?

I think it would be /post/@id and GUID is required. However I'd need to play around with it. Email me at tlovett88 [at] gmail if you get stuck.
