simple comments tag question

My comments are working but the “number of” comments feature isn’t showing up, mainly because I can’t figure out where to place the tag. Here’s what’s currently in my index.php:

[a href=”[?php comments_link(); ?]”]Comments[/a]

<?php comments_template(); // Get wp-comments.php template ?>

And the comments_number tag is, apparently, this:

<?php comments_number(‘zero’, ‘one’, ‘more’, ‘number’); ?>

But where, exactly, does it go? I’ve tried placing it after my comments link, before, and everywhere in between. Please advise. Thanks. [*note: I replaced every “<” with a “[” so that it would display properly above.]
