Hey, I am trying to open a server with the mod 'LARP' and the /tazer command doesn't work, so I took it from another script, and changed it, but it cannot be complied because of the line:
if(Tazer[playerid] == 0)
The errors are:
error 017: undefined symbol "Tazer"
warning 215: expression has no effect
error 001: expected token: ";", but found "]"
error 029: invalid expression, assumed zero
fatal error 107: too many error messages on one line

The full /tazer script is:

pawn Код:

if(strcmp(cmd, "/tazer", true) ==0 || strcmp(cmd, "/ta", true) ==0)
    {
        if(gTeam[playerid] == 2 || IsACop(playerid))
        {
            new weapons[13][2];
            for (new i = 0; i < 13; i++)
            {
                GetPlayerWeaponData(playerid, i, weapons[i][0], weapons[i][1]);
            }

            if(Tazer[playerid] == 0)
            {
                if(PlayerInfo[playerid][pTazerBullets] != 0)
                {
                    new ammo = weapons[2][1];
                    PreTazerAmmo[playerid] = ammo;
                    SafeGivePlayerWeapon(playerid, 23, PlayerInfo[playerid][pTazerBullets]);
                    Tazer[playerid] = 1;
                    AttachWeaponCorrectly(playerid, 24);
                    SetPlayerSkillLevel(playerid, WEAPONSKILL_PISTOL_SILENCED, 500);
                    OnePlayAnim(playerid,"SWORD","sword_block",50.0,0,1,1,1,1);
                    format(string, sizeof(string), "* %s hostlers his Desert Deagle and Unhostlers his Tazer.", sendername);
                    ProxDetector(30.0, playerid, string, COLOR_CHAT1,COLOR_CHAT2,COLOR_CHAT3,COLOR_CHAT4,COLOR_CHAT5);
                }
                else
                {
                    SendClientMessage(playerid, COLOR_GREY,"* No charges in the tazer!");
                    return 1;
                }
            }
            else
            {
                new ammo = weapons[2][1];
                PlayerInfo[playerid][pTazerBullets] = ammo;
                SafeGivePlayerWeapon(playerid, 24, PreTazerAmmo[playerid]);
                AttachWeaponCorrectly(playerid, 23);
                Tazer[playerid] = 0;
                ClearAnimations(playerid);
                SetPlayerSkillLevel(playerid, WEAPONSKILL_PISTOL_SILENCED, PlayerInfo[playerid][pSilenSkill]);
                format(string, sizeof(string), "* %s hostlers his tazer and Unhostlers his Deagle.", sendername);
                ProxDetector(30.0, playerid, string, COLOR_CHAT1,COLOR_CHAT2,COLOR_CHAT3,COLOR_CHAT4,COLOR_CHAT5);
            }
        }
        return 1;

What to do?
