price depend from attribute selected - how to?

[zoreli]

Hi

My shop is live, and now I want to do the following change.

Product from brand X from 50 ml and 100 ml where entered in products as 2 different products because they have different prices.

I want to enter this product from brand X only once and price should depend from the attribute selected, that is 50 ml or 100 ml.

Drop down list should be created so the customer can select one attribute ( 50 ml or 100 ml) and price should be changed according to the attribute.

How can I do this?

Regards, Zoran

Attribute name manager > create name size & select drop down or radio
Attribute value manager > create link to name and 50 & 100
Attribute controller mgr > add name + value to product enter price
Attribute controller mgr > add other name + value to product enter price
