Tokens in Views don't seem to work I added a new view (block) with FIELDS type. I added "Content: Comment count" to see the comments number, and in "Rewrite results" I clicked to "Output this field as a link", and added the token "[comment_count] == Content: Comment count" as link.
This link doesn't work.

When I add a different token, such as "[body] == Content: Body" or "[title] == Content: Title," the links still don't work.

Am I doing anything wrong?
I wanted to do the same thing.  I had a view of blog posts and at the bottom of the post I wanted to put a link that had a comment count that was a hyperlink (as I've seen this done on many other blogs).  The way I did it was like this:

Originally my view was set up to just display the full nodes.  I clicked to edit the view and went to Page Details->FORMAT->Show and changed the setting from "Content" to "Fields".

Added the following fields:

Content: Title
Content: Body
Content: Path
Content: Comment count


The key and answer to this post is: Even though I don't want to display the path on my view I need to add it as a field so that I can later use it when building the link for the comment count.  Also I believe the order of the paths is important, so the path field must come before the comment count field.  For the Content: Path field I checked the "Exclude from display" check box.  This hides the path from showing up in the view. Next under "REWRITE RESULTS", I checked "Use absolute link (begins with "http://")".  This is necessary for a proper URL when using the path as token below.

For the Content: Comment count field, under "REWRITE RESULTS" I checked "Output this field as a link" and in the "Link path" box I put [path].
