osCommerce Types of Shipping Modules Manage

I have 2 Types of Products ‘a’ & ‘b’.
Also I have 3 Modules Installed as Shipping Modules, say Flat, Table & UPS.

Requirement
case 1: In selection of Product Type ‘a’ - Flat has to come.
case 2: In selection of Product Type ‘b’ - UPS & Table has to come.
case 3: In selection of Product Type ‘a’ + ‘b’ - All 3 must come with users to have choice to select between UPS & Table.

I have managed case 1 and 2 by updating shopping_cart.php, checkout_shipping.php and includes/classes/shipping.php.
All I could not manage is case 3.

Anyone who has faced and solved such problems…

Hi.
Youre probably better off posting this on the OSCommerce or OSCmax forums where every user is using the same ecommerce package as you.

Thanks for your suggestion. But I did not get proper response from oscommerce Forum, yet I have not Tried on OSCmax.

Though it is not quite easily available, and the available one needs to code a bit.

It solved the Issue.

Thanks.
