AbleCommerce Shopping Cart Software

We build custom wheels, Currently i have a java based simple drop down box weight calculator. I have entered in all the weights in grams and it add up the selections.

With kits if i enter there weight in grams for all the different products. Kind of like how it adds up the price.

It dose not have to effect shipping prices, im talking about 10 to 80gram differences. It would be nice so customers can see the weight and price of there wheel at one time.

These would be "weight weenies" who want to save every gram they can.

Any way to display shipping weight of the kit on the kit page?

I currently use this vary basic weight calculator

Works vary well. But I have the same options in the kit page of my website so if i would display the product weight it would help many customers.
