Hello!
I have the channel where each entry is some car.
It is necessary for me that everyone registered member could have own assessment for each of car.
So, for example, when the new car (channel enty) was added, the member can give a mark of this car.
And then I need to collect these members marks and show the average mark on the car page.
Сould you tell me please what means I need in to realize my task?
