I am an amatuer so go easy with me !

I have installed K2 and understand catagories etc. So I have built a little content up. My problem is this: I cannot build menu links to my catagories and items. I try to , but I can't !!!!

When I go to Menu Manager in Joomla it appears to be there, but in Preview.... nothing. Do I have to alter something so that the K2 content appears in the Joomal menu?

Now I dont pretend to be an expert ...so Im hoping someone else is !

I'd be very grateful..and you would become I very nice person immediatley.
