it doesnt seem to be for a server (unless its for classic)
if it is for a server, put //#CLIENTSIDE above if (weaponfired) and use addweapons like he said, instead of toweapons.

as for it changing everyones numbers, .. thats because your commands are telling it to change everyones numbers, not a specific one :P

there are many ways to fix it..
one, you could make a command for each lotto ticket, or you could make it so the command is "change lotto a/b/c #"
then use something like:

tokenize #c;
this.lotto#t(2) = strtofloat(#t(3));
