I am having an issue with one of my customizations...

We have some products that we have free shipping enabled and wanted to offer expedited shipping. To accomplish this I simply removed the if statement here:

Code:
    // disable only when entire cart is free shipping
//    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_UPS_STATUS == 'True') ? true : false);
//    }
The problem is, while it still shows the ups quote, it doesn't update based on quantity. For example, an order of 5 items ships for the same cost as an order of one (ack!). I'm not sure where else to look to get the other shipping forms calculating correctly.

Thanks,
Phaylon
