thanks, i figured it out with votan example, and everything is uploaded.
I was afraid i wouldn't use properly the "self", but i would have used an addon variable to temporary store it if it hadn't worked.
surprisingly, it went so flawlessly that I had to recheck 3 times that i didn't edit in the pts folder instead of the live one


that's what i understood from harven's link, but I still dont understand why it doesn't simply replace the previous one when the context is the same. Not that it prevents me from doing what must be done, but it is still cloudy unclear.
