Number of comments after postheader in sidebar
 

Hello out there!

Im having a little issue, which I hope someone can help me with...

I would like so show the numbers of comments to a post in the sidebar. So after the post header in the sidebar, there e.g. is brackets with number of comments like (4). I've been told to use

comments_popup_link('(0)', '(1)', '(%)', '', '')

but I have no idea where to put it??

Hope someone knows?

Kind regards,
Charlotte
