free shipping if order contains certain product

[ianhg]

Currently two products have free shipping but all the other products have shipping costs. Is it possible to make an order that contains the free shipping item plus other items to be free shipping for the whole order?
Shipping cost is based on spend at a fixed sliding rate.
Thanks

What shipping modules do you have installed for managing the Free shipping and the Regular shipping right now?

Thanks for the speedy reply.
Table rate and freeshipping (freeshipper)
Table rate is set to overall spend.
Hope this helps

Customize the freeoptions.php and change the code to read:

      // disable only when entire cart is free shipping
      if (zen_get_shipping_enabled($this->code)) {
          $this->enabled = ((MODULE_SHIPPING_FREEOPTIONS_STATUS == 'True') ? true : false);
      }

// only show if products_id 11 or 12 are in the cart
      if (!IS_ADMIN_FLAG) {
        global $cart;
        $chk_prods = $_SESSION['cart']->in_cart_check('products_id','11')  + $_SESSION['cart']->in_cart_check('products_id','12');
        if ($chk_prods > 0) {
          $this->enabled = true;
        } else {
          $this->enabled = false;
        }
      }

      if ( ($this->enabled == true) && ((int)MODULE_SHIPPING_FREEOPTIONS_ZONE > 0) ) {

Change the tables.php to read:

    // disable only when entire cart is free shipping
    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_TABLE_STATUS == 'True') ? true : false);
    }

// do NOT show if products_id 11 or 12 are in the cart
      if (!IS_ADMIN_FLAG) {
        global $cart;
        $chk_prods = $_SESSION['cart']->in_cart_check('products_id','11')  + $_SESSION['cart']->in_cart_check('products_id','12');
        if ($chk_prods > 0) {
          $this->enabled = false;
        }
      }

    if ( ($this->enabled == true) && ((int)MODULE_SHIPPING_TABLE_ZONE > 0) ) {

where 11 and 12 are the products_id controlling this ...
