s2Member and bp

I would like to hide the ‘Listings’ tab to some users on my site.
I have installed s2member and the following code works (for the change avatar sub nav: it displays on level 2 and up);

<?php
function bp_remove_nav_item() {
if(current_user_cannot(“access_s2member_level2”))
global $bp;

bp_core_remove_subnav_item( $bp->profile->slug, ‘change-avatar’ );
}
add_action( ‘wp’, ‘bp_remove_nav_item’ );
?>

Thus I figured changing the code to;

<?php
function bp_remove_nav_item() {
if(current_user_cannot(“access_s2member_level2”))
global $bp;

bp_core_remove_nav_item(‘listings’);
}
add_action( ‘wp’, ‘bp_remove_nav_item’ );
?>

But that has hidden the listings tab from all users, any help would be appreciated, I know this is kind of out of the scope of this forum but I have failed to get help anywhere else!
Thanks
