need help, triggers

[fairyoggy]

I'm sorry, but what am I doing wrong?
How do I call triggers correctly?

-- client

function findplayer()
local zplayer = getLocalPlayer()
triggerServerEvent( 'findemail', zplayer)
end
addEvent("findplayer", true)
addEventHandler( "findplayer", localPlayer, findplayer )
addCommandHandler ( "e", findplayer )

-- server
function findemail(zplayer)
  outputChatBox("Your name: "..getPlayerName(zplayer))
end
addEvent("findemail",true)
addEventHandler("findemail",root,findemail)

I get an error: attempt to concatenate a boolean value

Use 'client' instead 'zplayer' (https://wiki.multitheftauto.com/wiki/TriggerServerEvent)

Zplayer on server-side is not an argument, its a root
