Hide hard coded shopping cart

I created a new role subscriber2. It has the identical capabilities of subscriber but I need the differentiation for different plugins to work.

I only want a subscriber2 role of the CURRENT SITE- to be able to see the Marketpress shopping cart that is hard coded at the top of the framemarket theme because I do not have global cart enabled and it confuses buyers. I pasted this in to gridmarket's header.php:

<div id="header-wrapper">
<div id="header">
if (current_user_can('read'))
<?php if ( class_exists( 'MarketPress' ) ) {

$settings = get_option('mp_settings');
if (!$settings['disable_cart']) {
<div id="cart-contents"><?php _e( 'Cart:', 'framemarket' ) ?> <span><?php echo sprintf(__('%s item(s)', 'framemarket' ), mp_items_count_in_cart()); ?></span></div>
<div id="mp-cartsmall">
<div id="toggle">
<?php _e( 'View Cart', 'framemarket' ) ?>

<?php _e( 'Hide Cart', 'framemarket' ) ?>

1) But subscribers from other blogs can see the cart and I don't want them to unless they are subscribers of the current blog. What code should I be using?
2) it is a paste of code from elsewhere Did I insert it the statements properly ?
