here i have a points script and a few others all in one!
I need to add a raffle system to this points system to allow to open a raffle with !giveaway new
then to enter people do !raffle and it minuses 50 points to enter and if they dont have 50 points is says you dont have enough points to enter this raffle!
Also it doesnt count if someone uses !raffle twice and it says you have alwready entered this raffle!
Thanks in advanced if u can do this for me im new to this sorta stuff!!
