Problem mit dcmd

Ich hab hier nen kleines Problemchen:
dcmd_popt(playerid,params[]) {

if(!strlen(params)) {
return SendClientMessage(playerid,COLOR_RED,"USAGE: /popt [playerid]");
}
new
pID=strval(params);
if(!IsPlayerConnected(pID)) {
return SendClientMessage(playerid,COLOR_RED,"Kein Spieler mit angegebener ID Online");
}
new PVEH;
PVEH = GetPlayerVehicleId(pID);
new panels, doors, lights, tires;
GetVehicleDamageStatus(vehicleid, panels, doors, lights, tires);
UpdateVehicleDamageStatus(vehicleid, panels, doors, lights, 15);
return 1;
}
Ich bekomme diese Fehler:

3 Errors.

Was isn hier falsch???

Ich find verdammt nochmal keinen Downloadlink, der funktioniert

@Darkfire: Dass ist R2 und nicht RC5.
FoxHound: Ich bin von seinem tutorial ausgegangen.

Ok, upgedatet habe ich...

Ich habs jetzt ohne dcmd gemacht
if(!strcmp(cmd,"/popt",true,5)) {
new
sID[128],
pID;
sID=strtok(cmdtext,idx);
if(!strlen(sID)) {
return SendClientMessage(playerid,COLOR_RED,"USAGE: /popt [playerid]");
}
pID=strval(sID);
if(!IsPlayerConnected(pID)) {
return SendClientMessage(playerid,COLOR_RED,"Kein Spieler mit angegebener ID Online");
}
new pvID;
pvID = GetPlayerVehicleID(pID);
new panels, doors, lights, tires;
GetVehicleDamageStatus(pvID, panels, doors, lights, tires);
UpdateVehicleDamageStatus(pvID, panels, doors, lights, 15);
}
Naja, villeicht nicht die intelligenteste Lösung, aber es funktioniert.
Trotzdem danke für eure Hilfe
