Free Shipping Options not working correctly

[enzo-ita]

Hi,
I am trying to achieve that when ot_freeshipping is false, and freeopitons is true in the shopping cart box appears the same warning/suggestion that appears when ot_freeshipping is true and freeoptions is false.

I have hacked the tpl_shopping_cart.php as follows for the section free shipping qualifier

//Begin free shipping qualifier
$free_ship_on = MODULE_SHIPPING_FREEOPTIONS_STATUS;

if ($free_ship_on == 'true') {
$free_limit = MODULE_SHIPPING_FREEOPTIONS_TOTAL_MIN;
if ($_SESSION['cart']->count_contents() > 0) {
$_SESSION['cart']->get_products();
$basket_total = $_SESSION['cart']->show_total();
if ($basket_total < $free_limit) {
$diff_to_free = ($free_limit - $basket_total);
$content .= '<span class="freeoptions">' . '<style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>Aggiungendo prodotti per '. $currencies->format($diff_to_free) .' <style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>avrai diritto alla spedizione gratuita!</b></span></span>' . '</span>';
} else {
$content .= '<span class="freeoptions">' . '<p style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>Complimenti! Hai diritto alla spedizione gratuita!</b></span></span>' . '</span>';
}
} else {
$content .= '<span class="freeshipping">' . 'Spedizione gratuita per ordini di ' . $currencies->format($free_limit) . ' or more.' . '</span>';
}
}
//End of free shipping qualifier

The original tpl_shopping_cart file is

//Begin free shipping qualifier
$free_ship_on = MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING;

if ($free_ship_on == 'true') {
$free_limit = MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER;
if ($_SESSION['cart']->count_contents() > 0) {
$_SESSION['cart']->get_products();
$basket_total = $_SESSION['cart']->show_total();
if ($basket_total < $free_limit) {
$diff_to_free = ($free_limit - $basket_total);
$content .= '<span class="freeshipping">' . '<style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>Aggiungendo prodotti per '. $currencies->format($diff_to_free) .' <style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>avrai diritto alla spedizione gratuita!</b></span></span>' . '</span>';
} else {
$content .= '<span class="freeshipping">' . '<p style="text-align: center; "><span style="font-size: small; "><span style="color: rgb(255, 0, 0); "><b>Complimenti! Hai diritto alla spedizione gratuita!</b></span></span>' . '</span>';
}
} else {
$content .= '<span class="freeshipping">' . 'Spedizione gratuita per ordini di ' . $currencies->format($free_limit) . ' or more.' . '</span>';
}
}
//End of free shipping qualifier

But it does not work.
The shipping qualifier does not appears.
Can someone help me in achieveing this?
Thanks
