Hi Kiran, Thanks very much for your reply.
I tried to initialize session.one_counter/two_counter/three_counter but it seems my understanding of the session variables in this case is not sufficient to get this right. Basically, I am stuck with this one. My aim is to count the clicks to image.id *1*, image.id *2* and image.id *3* separately, so I can compare them. If you could guide me in the right direction so I can have a better understanding and solve this problem or if you could correct my code, I would really appreciate it. Thanks again.
