i have wrote the coding from seeing this tutor
MY codings are
//First, of course we need to include these files first
#include <a_samp> //Without this, we won't be able to use all samp functions/callbacks
#include <a_mysql> //Without this, we won't be able to use all mysql functions
//Let's define our mysql settings
#define host "localhost" //This will be your mysql host. Default for xampp is localhost
#define user "root" //This will be your mysql username. Default for xampp is root
#define db "server" //This is your database name. Remember we have created a database called server before.
#define pass "root" //This is your mysql password. In xampp, the password didn't set. So leave it empty.
//dialogs
#define dregister 6287 //dialog register id
#define dlogin 6288 // ^
//Global variables. We will use them later

can u tell me whats the error i made
