comment-reply was not found

Hi,

i tested my theme with the theme-check

now i get the following error:

comment-reply was not found. *Required*
See: Migrating Plugins and Themes to 2.7/Enhanced Comment Display
Example: <?php if ( is_singular() ) wp_enqueue_script( “comment-reply” ); ?>

I can’t figure out what it means and how to fix it. I cannont find something like comment-reply in the twentyten theme to compare it with.

(i copied the comment functions from the twentyten theme)

thanks in advance,
Bas
