Ah, your problem's quite easy to solve. Just go to PKSV-UI's Script Generator and press the "Find Item Script" as the "Give Item Script" doesn't work unless you do some modifications with the script. Then just pick the item and the number of items you want, compile it, copy paste it to AdvanceMap or whatever you use and voila!
You have a perfectly working item script that requires no flags at all XD
As for the tutorial, believe me, it's almost done. I'm kinda excited to make it first, because it would be my first tutorial in ROM Hacking and second, it would help tons of scripters (you're not the only one waiting for it to be released)!
What happens to be your timezone, by the way?
