I need to add some PHP and HTML to a action hook in my WordPress site
I can not work out how to add the php so that Sub total text is translatable _e('Sub-total', 'wpsc')
That line throws a syntax error in my editor
PHP Code:
add_action('wpsc_before_form_of_shopping_cart', 'add_my_totals');

function add_my_totals() {
    $my_new_totals = '<table  class="wpsc_checkout_table table-4">
    <tr class="total_price">
   <td  class="wpsc_totals">
   <?php _e('Sub-total''wpsc'); ?>:
   </td>
   <td  class="wpsc_totals">
   <?php echo wpsc_cart_total_widgetfalsefalse ,false ); ?>
   </td>
   </tr>
</table>';

   echo "$my_new_totals";
   }
