Product attributes and add shipping weight

[zpupster 6]

hello support,

 

I am using Responsive OSCommerce 2.3.4, We started to use the product attributes.

 

We are using  it for different model numbers , but the  models have different shipping weights,

 

i have looked at a few of the add ons and most are for 2.2, and the one i found for 2.3 did not carry over the 

weight with the model number but had the customer pick their shipping weight as an attribute.

 

 

Could someone suggest an add on that would help me solve my problem.

 

many thanks,

 

Craig
