Help with create vehicle

Hi, I am scripting after a long time, I was making a system, I tried to compile it and I got some errors, It says something undefined symbol RCCAR what to do now?

Code:

---

new Float:x, Float:y, Float:z;

new rcol1 = random(100);

new rcol2 = random(50);

GetPlayerPos(playerid, Float:x, Float:y, Float:z);

RCCAR = CreateVehicle(441, Float:x, Float:y, Float:z, 365, rcol1, rcol2, 0)

PutPlayerInVehicle(playerid, RCCAR, 0);

rcused[playerid] = 1;

return 1;
