The idea behind this script is solid, but poorly executed, full of bugs, and basically unsupported in our case.
To be fair, a newer version of this script is out, but our project was a day away from entering production, so couldn't risk facing even more bugs / issues.
But I would have thought that our version would be the most stable to date, but we had showstopping bugs that forced us to disable most functionality to get it to work.
Support was absolutely useless too. We created a forum post, someone hijacked the thread with a similar but unrelated bug from the NEW version. The developer replied to the other unrelated user, ignored our critical bug fix request.
Basically no documentation. Conditional logic doesnt really work the way you think it should. Or at least the way I am doing it. I wouldnt know there is no documentation. AR forms is better and easy to understand quickly.
