Argument 2 got function Error in addEventHandler

[Tonythevato]

Debugscript message: Bad argument @ 'addEventHandler' [Expected element at argument 2,got function]

What does "got function" mean?

I tried to  change getRootElement() with root, but I've got the same error.

 

function speedmeter ()

outputChatBox("test", source)

end

addEventHandler("onPlayerVehicleEnter", getRootElement(), speedmeter)
