Create Custom Comments.php

<?php

if (is_category(‘ratings’)) {
comments_template(‘/comments45.php’);
}

else {
comments_template();
}

?>`

I want my comments.php to be different if it sees that the post is number 45 or ‘ratings’. This what I have posted here is within the single.php file and it currently does not work. My overall goal is to change some of the wording from comments to review in the text and have the order reversed.

Am I going about this the wrong way or I am right and having some syntax errors.

Appreciate the assistance
