Hello guys, today i need some help to script a phone number verification registration system to prevent troller registering and messing around. Here's what i want
-If the number you entered is already used, it will refuse and says "This Phone Number is Already Used!"
-I want to make this script exactly like in this server Address: 103.237.33.83:7777 (I dont mean to advertise)

Ok guys. that's it. I need help... So help will be very-very apriciated.
