Greeter and automatic notecard giver script

This is a script that will greet and give avatars a notecard without them touching anything.
Notecards will only be given once because a list is being created with avatars who allready recieved the notecard.
This can be resetted when you reset the list whit the command: reset list

excuz me but your script doesn't work...
nothing is happening and the touch "button" doesn't react when I touch...
it only counts visitors but doesn't give anything...
too bad because this would interest me too... a script that gives automatically a notecard and a LM....

hmm... just what I wanted but not working for me.... (insert sad face here)

when i used this...the is inventory notecard get sent to me not the person...is there something i have to change? would someone have a look at this and see if something is wrong pls...and ty for posting this
