Attach ped to vehicle by a command name

[Fabio(GNR)]

im trying to create something that attaches the player to the vehicle, like /attach nameofvehicleowner, it should get the vehicle "name" from the name entered at the command as parameter.... but i kinda got problems it says bad argument at getPlayerName and at getPedOccupiedVehicle, what i can understand... but i didnt really find much about command parameters, my script:

function attachtoveh ( playerSource, commandName, name ) 
names = getPlayerName ( name ) 
vehicle = getPedOccupiedVehicle ( names ) 
if vehicle then 
atttachElements ( playerSource, vehicle ) 
end 
end 
addCommandHandler ( "attach", attachtoveh ) 

( there probably comes that class=kw6, its from site i guess cause its not in my script )

try,

  
function attachtoveh ( playerSource, commandName, name ) 
names = getPlayerFromName ( name ) 
if names then 
vehicle = getPedOccupiedVehicle ( names ) 
if vehicle then 
attachElements ( playerSource, vehicle ) 
end 
end 
end 
addCommandHandler ( "attach", attachtoveh )
