Was daran Falsch?

Dann hast du irgendwo playerid wo es ganz und garnicht hinpasst :D.
Zum Beispiel bei OnGameModeInit.

Poste einfach mal die Zeilen

Probs mal so:

if (strcmp("/job1", cmdtext, true) == 0)//TAXI FAHRER
{
if(PlayerToPoint(3.0, playerid, 1222.9181,-1813.6516,16.5938))
{
gTeam[playerid]=TEAM_TAXI;
SetPlayerSkin(playerid, 60);
SetPlayerHealth(playerid, 100);
SendClientMessage(playerid,0x00FF00FF,"Du hast den Job :Taxi Fahrer angenommen.");
}
return 1;
}

if (strcmp("/job2", cmdtext, true) == 0)// POLIZEI
{
if(PlayerToPoint(3.0, playerid, 1546.4486,-1669.8274,13.4116))

SetPlayerSkin(playerid, 280);
SetPlayerHealth(playerid, 100);
SendClientMessage(playerid,0x00FF00FF,"Du hast den Job Polizist angenommen.");
}
return 1;
}

if (strcmp("/job3", cmdtext, true) == 0)// GRÄNZENWACHTER
{

}
