Hello friends ...here is my codefor my lvl system...i have a problem i want it to draw images for each lvl...But for some reason it is not working....here are all codes:

a part only_:

function win(ammo, killer, weapon, bodypart) 
    if (killer and getElementType(killer) == "player" and killer ~= source) then 
        local H = getElementData(killer, "XP") or 5 
        local S = getElementData(killer, "Level") 
        local killer1 = getPlayerName(killer) 
        local noob = getPlayerName(source) 
        local X = 1 
        setElementData(killer, "XP", tonumber(H)+X) 
        local H = tonumber(H) + X 
        if tonumber(H) == 2 then 
        setElementData(killer, "Level", "1") 
        elseif tonumber(H) == 5 then 
        setElementData(killer, "Level", "2") 
        elseif tonumber(H) == 10 then 
        setElementData(killer, "Level", "3") 

addEventHandler("onPlayerSpawn",root, 
function() 
    local account = getPlayerAccount(source) 
    local S = getElementData(killer, "Level") 
if tonumber(S) == 0 then 
setElementData(source,"Emblems","ranks/lvl_0.png") 
elseif tonumber(S) == 1 then 
setElementData(source,"Emblems","ranks/lvl_1.png") 
elseif tonumber(S) == 2 then 
setElementData(source,"Emblems","ranks/lvl_2.png") 
elseif tonumber(S) == 3 then 
setElementData(source,"Emblems","ranks/lvl_3.png") 
elseif tonumber(S) == 4 then 
setElementData(source,"Emblems","ranks/lvl_4.png") 
elseif tonumber(S) == 5 then 
setElementData(source,"Emblems","ranks/lvl_5.png") 
elseif tonumber(S) == 6 then 
setElementData(source,"Emblems","ranks/lvl_6.png") 
elseif tonumber(S) == 7 then 
setElementData(source,"Emblems","ranks/lvl_7.png") 
elseif tonumber(S) == 8 then 
setElementData(source,"Emblems","ranks/lvl_8.png") 
elseif tonumber(S) == 9 then 
setElementData(source,"Emblems","ranks/lvl_9.png") 
elseif tonumber(S) == 10 then 
setElementData(source,"Emblems","ranks/lvl_10.png") 
elseif tonumber(S) == 11 then 
setElementData(source,"Emblems","ranks/lvl_11.png") 
elseif tonumber(S) == 12 then 
setElementData(source,"Emblems","ranks/lvl_12.png") 
elseif tonumber(S) == 13 then 
setElementData(source,"Emblems","ranks/lvl_13.png") 
elseif tonumber(S) == 14 then 
setElementData(source,"Emblems","ranks/lvl_14.png") 
elseif tonumber(S) == 15 then 
setElementData(source,"Emblems","ranks/lvl_15.png") 
elseif tonumber(S) == 16 then 
setElementData(source,"Emblems","ranks/lvl_16.png") 
elseif tonumber(S) == 17 then 
setElementData(source,"Emblems","ranks/lvl_17.png") 
elseif tonumber(S) == 18 then 
setElementData(source,"Emblems","ranks/lvl_18.png") 
elseif tonumber(S) == 19 then 
setElementData(source,"Emblems","ranks/lvl_19.png") 
elseif tonumber(S) == 20 then 
setElementData(source,"Emblems","ranks/lvl_20.png") 
elseif tonumber(S) == 21 then 
setElementData(source,"Emblems","ranks/lvl_21.png") 
elseif tonumber(S) == 22 then 
setElementData(source,"Emblems","ranks/lvl_22.png") 
elseif tonumber(S) == 23 then 
setElementData(source,"Emblems","ranks/lvl_23.png") 
end 
end 
) 
  
addEventHandler("onPlayerSpawn",root, 
function () 
    local account = getPlayerAccount(source) 
    if isGuestAccount(account) then return end 
    local Emblems = getAccountData(account,"LV") 
    if emblems then 
        setElementData(source,"Emblems", emblems) 
end 
end 
) 

hud part:

  if XP then 
    dxDrawText("XP: "..XP, (336/1024)*sWidth, (745/768)*sHeight, (289/1024)*sWidth, (250/768)*sHeight, tocolor (255, 255, 255, 255), (0.85/1366)*sWidth,(0.9/768)*sHeight,"bankgothic","left","top",false,false,false,true) 
    end 
    if Level then 
    dxDrawText("LV: "..Level, (466/1024)*sWidth, (745/768)*sHeight, (289/1024)*sWidth, (250/768)*sHeight, tocolor (255, 255, 255, 255), (0.85/1366)*sWidth,(0.9/768)*sHeight,"bankgothic","left","top",false,false,false,true) 
    end 
    if emblems and fileExists ( ":experiences/ranks/lvl_"..Rank..".png" ) then 
    size = dxGetFontHeight((0.7/1366)*sWidth, "bankgothic") 
    dxDrawImage((557/1024)*sWidth, (745/768)*sHeight, size, size, ":experiences/ranks/lvl_"..Rank..".png") 

I would be happy ifthis topic would be done ....thx in advance

i see some erros(i think), yoy try get one number from one string?

EDIt : in debugscript it says server lua:4 Bad argument @get element data at argument 1 , got nil]

is the full code?

EDIt : in debugscript it says server lua:4 Bad argument @get element data (expected element at argument 1) , got nil]

    local account = getPlayerAccount(source) 
    local S = getElementData(killer, "Level") 

killer no definid

oh...how to definid it?

how you save the level and exp from player?

you have use setAccountData(onPlayerQuit), and (onPlayerLogin) use getAccountData and setElementData, to set the exp and level data to player.

ps: have other ways too, and you exp e level work fine?(only error in image or in all?)?

All work fine....pls just tell me how to definid it...ye the lvl and xp get saved...and my system working fine

oh...how to definid it?

Just want to know that

You don't need to 'definid' it, source is 'definid' by the event ( actually it's define(d)). Just replace killer with 'source' at the onPlayerspawn event.

still doesnt draws any image...
