[POMOC] Kako ovo da popravim?

E ovako,napravio sam polaganje i ja kad polazem radi mi sve,a drugi igraci ne mogu,stanu na prvi cp i koda ga nisu pokupili,jos stoji,a meni sve normalno radi,cuo sam da je problem u tome sto samo valjda ID 0 moze a ostali ne mogu,nzm nisam siguran,evo komanda:

pPolaganje,

if(strcmp(cmd, "/buydriving", true) == 0)

                    return 1;
              }
            if(PlayerInfo == 0)
            {
