BadArgument at @addeventhandler

[esporta05]

I have got pretty simple script. But my debugscript 3 is giving me error at my addeventhandler.

here is my script:

  
function Blood(loss,attacker,weapon,bodypart) 
local rootElement = getRootElement() 
local x, y, z = getElementPosition(source) 
local slapvalue = 5 
local timervalue = 10000 
local healthamount = 30 
   if loss > healthamount then 
      fxAddBlood ( x, y, z-2, 0.00000, 0.00000, 0.00000, 1, 1 ) 
      --setElementHealth ( targetPlayer, getElementHealth(targetPlayer) - slapvalue ) 
   end 
end 
addEventHandler ("OnClientPlayerDamage",rootElement,Blood)

try

function Blood(loss,attacker,weapon,bodypart) 
local x, y, z = getElementPosition(source) 
local slapvalue = 5 
local timervalue = 10000 
local healthamount = 30 
   if loss > healthamount then 
      fxAddBlood ( x, y, z-2, 0.00000, 0.00000, 0.00000, 1, 1 ) 
      --setElementHealth ( targetPlayer, getElementHealth(targetPlayer) - slapvalue ) 
   end 
end 
addEventHandler ("onClientPlayerDamage",root,Blood)
