I saw this video about numeric variables:
(of Feb 2013)
I applied it to my project. What I did is adding a trigger (+1 value when click on next) not only on the last slide of a chapter but on each and every slide (to be more precise).
the problem I see when using it is that if I take 5 times the same chapter, it keeps on adding a 1 value to my variable (which could give a result of 100% before I actually watched the whole module).
Is there a way I could tell the trigger to add the value only once? (or is there another way to go about it?)
Thanks for your help.
