onPlayerWasted

[crismar]

I'm building a UCP and I've some problems with this event handler that I never used before: onPlayerWasted

I have this simple function:

  
    function saveLifeStats() 
        local whoDied = getPlayerName(source) 
        outputChatBox("Ai murit cand aveai "..getElementData(whoDied, "lifetime"), whoDied, 255, 0, 0, false) 
    end 
    addEventHandler("onPlayerWasted", getRootElement(), saveLifeStats) 

The problem is I get this error when a player dies:

Attempt to concatenate a boolean value.

function saveLifeStats() 
outputChatBox("Ai murit cand aveai "..getElementData(source, "lifetime"), source, 255, 0, 0, false) 
end 
addEventHandler("onPlayerWasted", getRootElement(), saveLifeStats)
