comments dont link in theme

where would one insert this: <?php comments_template(); ?> into their single.php page if this is in fact the problem? I am using sliding door theme and the theme calls a double url with #comments at the end.

Look at where it’s located in one of your other pages in the theme and put it in the same general location in your single.php page…it will be near the bottom above the footer call.

Ok this bit of code is in my single.php file. Why then does clicking the leave a comment link bring up something like this:

This can be fixed by using the default navigation set up. I was trying to use the custom navigation.
