Trying to change footer

In the footer on the mainpage of the website where it tells you tags, dates, how many comments, and edit post we only want it to say "leave a comment" (the text being a link to the blog post where people can leave a comment). Client doesnt want it to announce how many people have commented on each blog post. Only a link that you can comment. what is the php to just show this? I have tried editing it with no success.

The page I'm trying to edit is the edit Post/Page INFO Items in the footer section where the php code tells the footer to display information about the post.

Thank you
