Another "spawnvehicle" question

[xxldoener]

So I already got my spawnvehicle-script to work. It works with spawnvehicle targetname vehicleid.

However, I wanted to add a function so that if you don't specify a target, the person who enters the command becomes the target. But somehow it doesn't work, I get the error BadArgument@getPlayerFromName in line 10, which means that the entry in line 5 doesn't work either. What am I doing wrong?

function spawnvehicle (thePlayer, commandname, target, vehicleid) 
if not vehicleid then 
if tonumber (target) then 
vehicleid = tonumber (target) 
target = (thePlayer) 
else 
outputChatBox("Invalid VehicleID was given", thePlayer) 
end 
end 
local targetp = getPlayerFromName (target) 
if targetp then 
local x, y, z = getElementPosition ( targetp ) 
local spawnedvehicle = createVehicle (tonumber (vehicleid), x+2, y+2, z+1) 
if not spawnedvehicle then outputChatBox("Invalid VehicleID was given", thePlayer) 
end 
else 
outputChatBox("Invalid player specified", thePlayer) 
end 
end 
addCommandHandler ( "spawnvehicle", spawnvehicle )

function spawnvehicle ( thePlayer, commandname, target, vehicleid ) 
    local vehicleid = tonumber ( vehicleid ) 
    if ( not vehicleid ) then 
        outputChatBox ( "Invalid VehicleID was given", thePlayer ) 
    else 
        local targetp = getPlayerFromName ( target ) 
        if ( not targetp ) then -- If the target is not online. 
            targetp = thePlayer -- Set the "targetp" variable to the player who used the command. 
        end 
        local x, y, z = getElementPosition ( targetp ) 
        local spawnedvehicle = createVehicle ( vehicleid, x + 2, y + 2, z + 1 ) 
        if ( not spawnedvehicle ) then  
            outputChatBox ( "Invalid VehicleID was given", thePlayer ) 
        end 
    end 
end 
addCommandHandler ( "spawnvehicle", spawnvehicle )

I think that is not what I want. I want to receive a message that says "Invalid target specified" if the target player is not online, but I want to spawn a vehicle next to the player who entred the command if no target is specified.

For example, I am player1 and player2 is also online.

If I enter spawnvehicle player3 500 - A message should appear telling "Invalid target specified"

If I enter spawnvehicle 500 - A Vehicle with the ID 500 should appear next to me (being the player who entered the command)
