TOPIC:

Hi,
i have quite a stupid question: On the top of my configuration page stands:

Shipment based on general rules (weight, products, amount) per country-zones

instead of:

Shipment based on general rules (weight, products, amount) per country-zones, including arithmetic expression

I suppose, that could be the reason for very few parameters, that I can change (weight and amount).
I would be very thankful for any advice.

The "including arithmetic expressions" is the difference between the "Shipping by Rules" and the "Advanced Shipping by Rules" plugin. You apparently have the basic version installed and in use.

In both versions, you have the same variables available (except for the coupon code, which is available in the advanced version only). See open-tools.net/documentation/shipping-by...emart.html#variables
You can use all variables in the comparisons, but you cannot change any of them. You can only use them to calculate a shipping rate from their values.

Problem solved.
