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'))
************************
