Dear Reinhold,

I use your advanced plugin on my marketplace (woocommerce/wc vendors)
I configure your plugin to respect the delivery rules of my sellers.

I have a question about the calculation of the shipping cost when a buyer choose 2 separate products from the same vendor.

Here is my formula for the calculation of the sum of the shipping costs.
It is based on the SKU because there is a shipping cost per product (and per quantity).

Variable=Shippingcalc;Value=0
Variable=Shippingcalc; "product1" in SKUs;evaluate_for_vendors(Articles,"VendorA")==1;Value=7
Variable=Shippingcalc; "product2" in SKUs;evaluate_for_vendors(Articles,"VendorA")==1;Value=5
Shipping=Shippingcalc

If a buyer add 1 product1 and 1 product2 in the shopping cart, the displayed amount should be 7+5=12.
But the amount displayed is 14 (twice the first shipping cost).

Is there a mistake in my code?

Thanks in advance.

Arnaud

Dear Arnaud,
If you have different shipping costs per product, and a limited number of products, I would suggest to use evaluate_for_products instead and include the articles directly in the value:
Best regards,

PS: The "mistake" in your code is the assumption that shipping costs are specified per product. You need to explicitly include the quantity in the cost. And the other mistake is the assumption that the values are automatically added, i.e. you need to use Value=Shippingcalc+7*evaluate_for_....

Problem solved.
