product dimensions value problem

[mawips]

Hello all,

I have a problem with products that I want to sell using Prestashop engine.

I have products that have different lenght, but the rest of dimensions are the same.

I want to create a product with different values to choose from. I don't want to make those as separate products.

The problem appears when it comes to shipment costs.

In the new Presta 1.5 I can describe all dimensions of a product. But when I want to add a new value (lenght), it can only affect the weight of the product (and the price of course).

 

Example:

 

Product X Value 1 - 96mm width X 120mm height X 2450mm length - 28 kg weight - shipping cost 333 PLN

Product X Value 2 - 96mm width X 120mm height X 2760mm length - 32 kg weight - shipping cost 460 PLN

Product X Value 3 - 96mm width X 120mm height X 3060mm length - 36 kg weight - shipping cost 460 PLN

 

If it's the only product, than I can calculate it by weight, but:

 

Product XYX Value 1 - 96mm width X 120mm height X 2450mm length - 32 kg weight - shipping cost 333 PLN

Product XYX Value 2 - 96mm width X 120mm height X 2760mm length - 36 kg weight - shipping cost 460 PLN

Product XYX Value 3 - 96mm width X 120mm height X 3060mm length - 40 kg weight - shipping cost 460 PLN

 

Do someone has an idea how to fix this problem?
