Free shipping based on subtotal rather than overall total

[freakystreak 9]

I am using OSCommerce Frozen and have the shipping's  'allow free shipping' option set to true(within order totals). I need to make the free shipping option be based off the subtotal amount rather than the total amount within the shopping cart. Is this possible? I need to have free shipping activated when the subtotal is over £118. At the moment free shipping is showing when the overall total ( including subtotal and tax) is over £99. In simple terms i want free shipping to trigger when the sub total order value is £99.

@freakystreakIn includes/modules/order_total/ot_shipping.php, find

        if ( ($pass == true) && ( ($order->info['total'] - $order->info['shipping_cost']) >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) ) {

and change the 'total' to 'subtotal'
