Trying to get the PayPal Express Checkout button to show in my sidecart:

I tried this "moving of the PayPal logic" into my side cart and have had no luck... I suck at code.

Code:
if ($_SESSION['cart']->count_contents() > 0) {
    $content .= '<hr />';
    $content .= '<div class="cartBoxTotal">' . $currencies->format($_SESSION['cart']->show_total()) . '</div>';
    $content .= '<br class="clearBoth" />';
    $content .= '<a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a><br /> Or Use <br />';
    $content .= '<br class="clearBoth" />';
I THINK I NEED THE PAYPAL BUTTON CODE HERE?????
  }
I figured I could just copy and paste the code from the full page shopping cart page (tpl_shopping_cart_default.php - where the PayPal Express Checkout button does show up)

I've tried to figure this out for two days... any help is greatly appreciated.
