Lua error in my addon

[riobusor66]

Hi, I need help with my script, I can spawn an npc(in the entity menu) the npc can open menu with the use key. I use net function like this in server side
function ENT:Use(act, ply, use, val)
    if IsValid(ply) and ply:IsPlayer() then
        net.Start("HitmanUse")
        net.Send(ply)
    end
end
and this in client side
net.Receive("HitmanUse", OpenHitmanUse())
the OpenHitmanUse function is declared like this
local function OpenHitmanUse()
.......
end
this code work but if I change this code to
function ENT:Use(act, ply, use, val)
    if IsValid(ply) and ply:IsPlayer() then
        net.Start("HitmanUse")
        net.WriteEntity(ply)
        net.Send(ply)
    end
end

net.Receive("HitmanUse", function(len, pl)
    OpenHitmanUse(pl)
end)

local function OpenHitmanUse(pl)
THE SAME CODE HERE.....
end
the code not work, no error in console and the addon menu named "hitman" in the entity menu is not showed and the npc dispawn in game.

Sorry for my english i'm french, Thanks.

for
net.Receive("HitmanUse", OpenHitmanUse())
you don't need the parenthesis after the function name
net.Receive("HitmanUse", OpenHitmanUse)
would work

net.Send is serverside only, on the client you need to use net.SendToServer()
