Editing TTT : Error using a variable as a function argument

[Хум]

I'm working on editing some of the TTT files and I've come to a stop. More specifically, an error I'm pretty much baffled by. Here's my code:

[lua]
... CODE ...
if roundtype == ROUND_DM then
local live = {}
local p2 = {}
for _, ply in pairs( player.GetAll() ) do
if ply:Alive() then
table.insert( live, ply )
end
end
if #live == 2 then
p2[1] = live[1]
p2[2] = live[2]
elseif #live == 1 then
for _, pl in pairs( p2 ) do
if pl == live[_] then
winner = pl
if _ == 1 then
loser = p2[2]
else
loser = p2[1]
end
end
end
if not p2[1] or not p2[2] then winner = live[1] end
if #player.GetAll() == 1 then
EndRound( WIN_TIMELIMIT, winner )
else
EndRound( WIN_TRAITOR, winner, loser )
end
elseif #live == 0 then
EndRound( WIN_NONE )
end
elseif roundtype == ROUND_TIME then
... CODE ...

function EndRound(type, ply, kill)
//PrintResultMessage(type)

if type == WIN_TRAITOR then
LANG.Msg( "win_innocent", {ply = ply:Nick(), kills = kill:Nick()} )
elseif type == WIN_INNOCENT then
LANG.Msg( "win_time", {ply = ply:Nick(), kills = kill} )
elseif type == WIN_NONE then
LANG.Msg( "win_traitor" )
elseif type == WIN_TIMELIMIT then
LANG.Msg( "win_timelimit", {ply = ply:Nick()} )
end

... CODE ...
[/lua]

[lua]
LANG.Msg( "win_innocent", {ply = ply:Nick(), kills = kill:Nick()} )
[/lua]
This line is what gives me errors, saying that [lua] kill isn't valid [/lua].
I am not sure why it would do that, since the script gets the last two players and retrieves them when there is only one left alive. Why would kill be nil, considering I'm passing that argument via the function?

As usual, try printing it in the console first.
Put "print( type, ply, kill )" at 1st line of the function.
