pawn Код:

CMD:radar(playerid, params[])
{

replace that with

pawn Код:

if (strcmp("/radar", cmdtext, true, 6) == 0)
{

But i think it wont work because you dont use

pawn Код:

PlayerInfo[playerid][pLeader]
PlayerInfo[playerid][pMember]
ProxDetector
VehicleNames[GetVehicleModel(GetPlayerVehicleID(i)) // Easy to fix
