Joe,
Glad the issue is sorted out.
If you haven't already, I suggest you also take a look at the web2py
book's 'Session' section:

Hello Kiran,
Yes, I know I wont be able to track the total number of clicks across
all users. I want to serve a targeted ad banner to a user based on
which category of images he or she clicks the most. In other words,
different users will see different banners based on their individual
likes or dislikes.
Thank you so much for helping me with this. I appreciate your answer.
*Your solution works perfectly*. My problem is solved now and I
learned something about session variables.
Thanks again.
Cheers,
Joe

So you want to keep track of the number of a times a user (in a
user's session) clicked on the images 1 to 3. Using a session to
capture this count, you won't be able to track the total number of
clicks across all users (just saying)
My understanding is:
* the url comes in as 'show/some_number'
* you use the the 'some_number' to query the database for a
matching 'image'.
The changes you would need to make are:
if image.id <http://image.id> == 1:
session.one_counter = (session.one_counter or 0) + 1
if image.id <http://image.id> == 2:

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 <http://image.id> *1*,
image.id <http://image.id> *2* and image.id <http://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.
Cheers,

You seem to be incrementing 'counter' in the session (the
counter is user session specific then). Also, you are using
session.one_counter/two_counter/three_counter, without having
initialized it. Is that a typo?

I am trying to use session.counter to count clicks on images
on a page.
My problem is that my session.counter is not counting...
I am doing something wrong, not sure exactly what.
I am pretty sure the issue is the/if image.id
<http://image.id> == 1/
I'd appreciate some help with this.
*Controller:*
def index():
images = db().select(db.image.ALL, orderby=db.image.id
<http://db.image.id>)
return dict(images=images)
def show():
image = db.image(request.args(0,cast=int)) or
redirect(URL('index'))
one_counter = []
two_counter = []
three_counter = []
if image.id <http://image.id> == 1:
session.counter = (session.counter or 0)+1
one_counter=session.one_counter
elif image.id <http://image.id> == 2:
session.counter = (session.counter or 0)+1
two_counter=session.two_counter
elif image.id <http://image.id> == 3:
session.counter = (session.counter or 0)+1
three_counter=session.three_counter
return dict(image=image)
def download():
return response.download(request, db)
*View:*
show:
<h3>{{=0 if session.one_counter is None else
session.one_counter}}</h3>
<h3>{{=0 if session.two_counter is None else
session.two_counter}}</h3>
<h3>{{=0 if session.three_counter is None else
session.three_counter}}</h3>
