getElementPosition error argument

[BorderLine]

hi everyone. Well i have a problem and i dont know why

i have this

function zomb(cplayer) 
x,y,z = getElementPosition(cplayer) 
exports [ "slothBot" ]:spawnBot ( x,y,z, 0, 10, 0, 0, Zombies, 0, "hunting", true ) 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), zomb) 

The problem is, error in argument of getElementPosition. say nill argument.

I try many ways but doesnt work.

Thanks for your time

Try this

function zomb() 
    local x, y, z = getElementPosition(source) 
    exports [ "slothBot" ]:spawnBot ( x, y, z, 0, 10, 0, 0, Zombies, 0, "hunting", true ) 
end 
addEventHandler ( "onPlayerSpawn", getRootElement(), zomb)

function zomb(posX, posY, posZ) 
     exports["slothBot"]:spawnBot(posX, posY, posZ, 0, 10, 0, 0, Zombies, 0, "hunting", true) 
     -- Zombies is defined? it should be a team element. 
end 
addEventHandler("onPlayerSpawn", root, zomb)
