Vehicle plate

[xyz]

function plate(player, cmdName, text) 
local acc = getPlayerAccount(player) 
local accn = getAccountName(acc) 
    local occveh = getPedOccupiedVehicle(player) 
        if occveh then 
            if getElementData(occveh, "vehsAcc") == accn and text then -- This checks if the vehicle is the player's personal veh. If you're wondering 
                setVehiclePlateText(occveh, text) 
                outputChatBox("Plate text changed!", player, 0, 255, 0) 
                    else 
                end 
                    outputChatBox("This isn't your personal vehicle!", player, 255, 0, 0)    
                        else 
                    outputChatBox("You must be in a vehicle to change the plate!", player,  255, 0, 0) 
            end 
end 
addCommandHandler("plate", plate) 

The problem is, that when everything is correct it still outputs "You must be in a vehicle to change the plate!", how can I fix that?
