Ok here is what I see as the problem.
What you are doing is setting variable as 0 every time you start a webpage.
Every time you start a webpage this entire file is look over as if it
was never seen before. Doing so is a great thing but you have to take
the approch differently knowing this.
For example here...
variable = 0
session.variable = variable
this resets it to 0 at every load.
What you should do is something like this because you have data that
needs to be checked first...
if not session.variable:
session.variable = 0
This then checks if you have any data there (if it doesn't it returns None)
Place that at the beginning of your file where you have variable = 0 and
see if that is more of what you expected.

Here is some code from the controller file:
************************
variable = 0
def index()
some operations with the variable...
def minorvar():
variable-=1
redirect(URL('index'))
************************
I also tried with this code, but the variable isn't changed after
redirecting it to the index-function:
************************
variable = 0
session. variable = variable
def index()
variable=session. variable
some operations with the variable...
def minorvar():
session.variable-=1
redirect(URL('index'))
************************

I would recommend that you use session.variable if that's what you want
to do.
Could we see the controller for the page before? I wonder if there is a
way we could put the action in there to make your code a bit cleaner.

Thanks for the replies. I wrote a special def for the operation:
def minorvar():
variable-=1
redirect(URL('index'))
...but I get an error that says that:
local variable 'variable' referenced before assignment
...even though I've defined the variable as global at the beginning of
the controller file.

Yup... I think you should do that in the controller before you pass it.
It's a two second job so not hard to do.
That and session.variable=-1 is well... -1 it should be variable-=1.
On the other had, you may be going for -1 :P and you may be using a
special loop or something that needs to change as the page is formated.
Always exceptions when you have to print from the top down and build the
page before sending it to the client. :D

Hi,
My problem is that I want to make a {{=A...}} tag that also changes
the value of the variable session.variable, and I don't know how to do
this. I tried with:
{{=A(("[< ]"), session.variable=-1, _href=URL('function'))}}
...but it didn't work.
Hi.
I'm not sure if that is a good way to program. Some would say, that
you shouldn't change variable in the view so I don't think (I might be
wrong, though), that it could work like that.
What would you like to achieve?
