Adding extra cost to shipping module

Hy,

I`m search for extension like this but i have an qustion for this extension:
http://www.opencart.com/index.php?route ... n_id=11904

If i buy 2 products with different shipping cost ( shipping cost standard is 10$ )... 1 products cost 100$ and shipping cost adding extra +5 $ and and another products cost 150$ with shipping cost adding extra +10$
Now total i want to be 100$(first product ) + 150$( secound product) + 10(shipping cost standard) + 10 ( extra shipping cost from secound product... becouse is the highest extra shipping value added) = 270$.

I dont wanna to add extra cost for all products and acumulate all extra cost... just the biggest extra shipping cost to be added on standard module .

Can anyone show me an extension who make`s that ?

Thx

You can use Product-Based Shipping to set up charges for each product (or group of products) and then choose the highest among them, in addition to a standard shipping charge. You have to create a rate for each group of products, though, so if you have a lot of products it may not be the ideal solution for you.

Yes i have...

Recently i migrate from cs cart to opencart. In old platform cs cart i have an option on editing product page... Add extra shipping ... and there i put 5,10 everything i want, and when a customer buy this products, in confirmation page ... it display the standard shipping cost and the highest extra cost for shipping .

@Johnathan: I found an extension... but i want to know if this extension make that i want..

Can you check it? jeff8j not respond on mail and comments...

I can't comment on another developer's extension, since I've never used them, so you'd need to keep hounding the developer for some support. If they don't answer within a few days, I'd be wary of buying from them.

Thx a lot. I found a solution... an developer save me !

Now i have a BIIGGGG PROBLEM with currency:O !
