GLua Variable Reassignment Syntax

[EFEX03]

Hey guys! I am trying to manipulate text position depending on the highest point of an entity. I have this code but it does not work properly. Nothing is drawing. When I remove the variable reassignment stuff, the code works fine. I am not sure why this is not working how it is supposed. Does GLua not support what I am trying do?

Code:

function DrawNPCData()
local localplayer = LocalPlayer()
local tr = localplayer:GetEyeTrace()
local npc_bar = Material("materials/npc_bar.png")
local NPC_View_Small = {150, 50}
local NPC_View_Normal = {300, 75}
local NPC_View_Large = {600, 150}
local max_view = 0
local min_view = 0

for _, npc in pairs(ents.GetAll()) do
local pos = (npc:GetPos() + Vector(0,0,75)):ToScreen()
local alpha = 255 - math.Clamp(npc:GetPos():Distance(localplayer:GetPos()) * 0.6, 0, 255)
local npc_bounds = npc:OBBMaxs()
local npc_top = npc_bounds[3]

if npc_bounds[3] >= 0 and npc_bounds[3] <= 60 then
local npc_top = npc_bounds[3] - 75
local max_view = NPC_View_Small[1]
local min_view = NPC_View_Small[2]
elseif npc_bounds[3] >= 61 and npc_bounds[3] <= 90 then
local npc_top = npc_bounds[3]
local max_view = NPC_View_Normal[1]
local min_view = NPC_View_Normal[2]
elseif npc_bounds[3] >= 90 and npc_bounds[3] <= 99999 then
local npc_top = npc_bounds[3]
local max_view = NPC_View_Large[1]
local min_view = NPC_View_Large[2]

if npc:IsValid() and npc:IsNPC() and (npc:GetPos():Distance(localplayer:GetPos()) <= max_view and npc:GetPos():Distance(localplayer:GetPos()) >= min_view) then
--print(npc_bounds)
surface.SetMaterial(npc_bar)
        surface.SetDrawColor(255,255,255,alpha)
        surface.DrawTexturedRect(pos.x-130, pos.y-npc_top, 250, 80)

--draw.RoundedBox(0, pos.x-80, pos.y-65, 150, 10, Color(0, 0, 0, 175))
--draw.RoundedBox(0, pos.x-80, pos.y-65, 150 * (npc:Health() / npc:GetMaxHealth()), 10, Color(255, 0, 0, 155))
--draw.SimpleText("prank", HUDFontBar, pos.x, pos.y+25, Color( 255, 255, 255, 255 ))
-- end
end
end
end
end
hook.Add("HUDPaint", "NPCDataDrawing", DrawNPCData)

You're declaring local variables inside a deeper scope than where you're using them
