Hi!
Thx a bunch for your answers, truly appreciated! Based on your tips I figured it out.
The problem with my advanced action was that it caontained the Expression var_paper = 1+1 ( I had thought that this would assign the value with 1 the first time the action was run, and then increment by 1 for each further time)
I changed the Expression to var_paper=var_paper+1 and for some reason this worked just as I had planned.
Not sure if I totally understood the logic, but it works just as wanted now
Thx again!
