Blog with file attachment

When i write a blog, i want the opportunity to attach a file to the blog. I created the form, but i can't see the attached file in the river.

I did it like it was described in the developer guides "file System". I modified the form and the action like the description.

Can anybody help me? I'm working since hours and there is no idea left how to do...
