Map Vote system not working? (custom made)

[LewisUK]

So i am using this code, (calling a ulx votemap2 at the end) but i get an error:

Code:
[lua]
function ulx.doVoteMod( title, options, callback, timeout, filter, noecho, ... )
timeout = timeout or 20

local rp = RecipientFilter()

rp:AddAllPlayers()
local voters = #player.GetAll()

umsg.Start( "ulx_vote", rp )
umsg.String( title )
umsg.Short( timeout )
ULib.umsgSend( options )
umsg.End()

timer.Create( "ULXVoteTimeout", timeout, 1, ulx.voteDone )
end

function ulx.voteCallback( ply, command, argv )
if not voteInProgress then
ULib.tsayError( ply, "There is not a vote in progress" )
return
end

if not argv[ 1 ] or not tonumber( argv[ 1 ] ) or not voteInProgress.options[ tonumber( argv[ 1 ] ) ] then
ULib.tsayError( ply, "Invalid or out of range vote." )
return
end

if ply.ulxVoted then
ULib.tsayError( ply, "You have already voted!" )
return
end

local echo = util.tobool( GetConVarNumber( "ulx_voteEcho" ) )
local id = tonumber( argv[ 1 ] )
voteInProgress.results[ id ] = voteInProgress.results[ id ] or 0
voteInProgress.results[ id ] = voteInProgress.results[ id ] + 1

voteInProgress.votes = voteInProgress.votes + 1

ply.ulxVoted = true -- Tag them as having voted

local str = ply:Nick() .. " voted for: " .. voteInProgress.options[ id ]
if echo and not voteInProgress.noecho then
ULib.tsay( _, str ) -- TODO, color?
end
ulx.logString( str )
if game.IsDedicated() then Msg( str .. "n" ) end

if voteInProgress.votes >= voteInProgress.voters then
timer.Destroy( "ULXVoteTimeout" )
ulx.voteDone()
end
end
if SERVER then concommand.Add( "ulx_vote", ulx.voteCallback ) end

function ulx.voteDone()
local players = player.GetAll()
for _, ply in ipairs( players ) do -- Clear voting tags
ply.ulxVoted = nil
end

local vip = voteInProgress
voteInProgress = nil
ULib.pcallError( vip.callback, vip, unpack( vip.args, 1, 10 ) ) -- Unpack is explicit in length to avoid odd LuaJIT quirk.
end

local function CheckTheRound()
if GetGlobalInt("ttt_rounds_left") == 1 then
VoteForNextMap("ttt_67thway_v4","ttt_67thway_v3","ttt_vessel","ttt_whitehouse_b2","ttt_slender_v2","ttt_rooftops_a2","ttt_crummycradle_a4")
RunConsoleCommand("ulx","csay","A votemap has been initiated to pick the next map!")

elseif GetGlobalInt("ttt_rounds_left") == 0 then
RunConsoleCommand("ulx","csay","The map will change in 5 seconds.")
timer.Create( "my_timer", 5, 0, function() ULib.consoleCommand( "changelevel " .. changeTo .. "n" ) end)
end
end
hook.Add("TTTEndRound","blah",CheckTheRound)

local function voteMapDoneOTHER( t, argv, ply )
local results = t.results
local winner
local winnernum = 0
for id, numvotes in pairs( results ) do
if numvotes > winnernum then
winner = id
winnernum = numvotes
end
end

if not winner then
str = "Vote results: No one voted, the next map will be picked randomly."
RunConsoleCommand( "ulx", "csay", str )
changeTo = t.options[ math.random(1,#t.options) ]
str = "The next map will be "..changeTo.."."
timer.Create( "msg1", 4, 1, function() RunConsoleCommand( "ulx", "csay", str ) end)
str = "The map will be changed next round."
timer.Create( "msg2", 8, 1, function() RunConsoleCommand( "ulx", "csay", str ) end)
else
str = "Votemap results: '" .. t.options[ winner ] .. "' won. (" .. winnernum .. "/" .. t.voters .. ")"
RunConsoleCommand( "ulx", "csay", str )
changeTo = t.options[ winner ]
str = "The map will be changed next round."
timer.Create( "msg1", 4, 1, function() RunConsoleCommand( "ulx", "csay", str ) end)
end

RunConsoleCommand( "ulx", "csay", str ) -- TODO, color?
ulx.logString( str )
if game.IsDedicated() then Msg( str .. "n" ) end
end

function VoteForNextMap( ... )
local argv = { ... }
ulx.doVoteMod( "Change map to..", argv, voteMapDoneOTHER, _, _, _, argv, calling_ply )
end
[/lua]

The error:
[lua]

[Error] gamemodes/terrortown/gamemode/RGScripts.lua:67: attempt to index local 'vip' (a nil value)

1.unknown -gamemodes/terrortown/gamemode/RGScripts.lua:67

Timer Failed! [UlxVoteTimeout] [@gamemodes/terrortown/gamemode/RGScripts.lua (line 17)]

Any help appriciated, thanks!

Also, when you vote, it errors ingame as "there is no vote currently running"

On line 66 you've set voteInProgress to nil which it tries to use on the next line...

Line 16

[lua]
voteInProgress = { callback=callback, options=options, title=title, results={}, voters=voters, votes=0, noecho=noecho, args={...} }
[/lua]

adding that in at line 16 fixed it all, works now!
