I need help with my game script it wont clone the gun to the players backpack? [Unanswered]

So I got a function and a for loop set up and everything but for some reason it just won't clone anything to anywhere

Here's my script

local mapDirectory = game.Lighting.Maps 
local RoundName = game.Lighting.RoundNames								
while true do  							
local maps = mapDirectory:getChildren() 
local RoundNames = RoundName:getChildren()
										
if #maps == 0 then   					
	print("Maps not found! Selfremoving...") 
	script:remove()  					
	return								
end 						 			
h = Instance.new("Hint")				
timeMin = 5 							
timeSec = 0 							
										
function Countdown(min,sec,txt,pretxt)	
h.Parent = game.Workspace				
for i = 1, sec + (min * 60) + 1 do		
if sec < 10 and min == 0 then			
h.Text = pretxt.." 0:0"..sec.." "..txt	
elseif sec < 10 then					
h.Text = pretxt.." "..min..":0"..sec.." "..txt
elseif sec + (min * 60) < 60 then		
h.Text = pretxt.." 0:"..sec.." "..txt	
elseif sec + (min * 60) > 59 then		
h.Text = pretxt.." "..min..":"..sec.." "..txt
end										
wait(1)									
if sec > 0 then							
sec = sec - 1							
elseif sec == 0 and min ~= 0 then		
sec = 59								
min = min - 1							
elseif sec == 0 and min == 0 then		
print("Ended")							
end										
end  									
h.Parent = nil							
end										
pretext = "Time untill the next round..." 
local pickedRoundName = "Team Deathmatch"
text = "Round Chosen..." ..pickedRoundName.." have fun!"		
h:remove()					
msg = Instance.new("Hint")      		
msg.Parent = workspace     				
msg.Text = "Sorry for any errors"  		
wait(0)									
msg.Text = "...Choosing a new map..."	
wait(1)									
local pickedMap = maps[math.random(1, #maps)] 
local pickedMapClone = pickedMap:clone()
pickedMapClone.Parent = game.Workspace  
pickedMapClone:makeJoints()  			
wait(2.5)								
msg.Text = "Map chosen is: " ..pickedMapClone.Name.."."  	
wait(2)									
msg.Text = "Kill everybody at..." ..pickedMapClone.Name.." to survive."  
wait(2)									
msg:remove() 							
					
		
									
local pplz = game.Players:GetChildren()	
local team1 = CFrame.new(100, 11.5, -69.5)
local team2 = CFrame.new(-186, 11.5, 106.5)

function GiveWep()
    local a = game.Lighting.Gun:Clone()
    a.Parent = pplz.Backpack 
end

for i = 1,#pplz do 						
if pplz[i].TeamColor == BrickColor.new("Bright red") and pplz[i] ~= nil and pplz[i].Character:FindFirstChild("Torso") ~= nil then-- change to team1's TeamColor--SCRIPTED BY CLIMAXIMUS						
pplz[i].Character.Torso.CFrame = CFrame.new(100, 12.5, -69.5) 
									
elseif pplz[i].TeamColor == BrickColor.new("Bright blue") and  pplz[i] ~= nil and pplz[i].Character:FindFirstChild("Torso") ~= nil then--change to team2's TeamColor--SCRIPTED BY CLIMAXIMUS
pplz[i].Character.Torso.CFrame = CFrame.new( -186, 11.5, 106.5)

for i = 1,#pplz do 
    local a = game.Lighting.Gun:Clone()
    a.Parent = pplz.Backpack 
end

end end    								
print("Map inserted: " .. pickedMap.Name) 
Countdown(timeMin,timeSec,text,pretext)
pickedMapClone:remove()  			
										
wait(1)							
										
local pplz = game.Players:GetChildren()
local lobby = CFrame.new(-130.55, 148.67, -11.9)
for i = 1,#pplz do						
if pplz[i] ~= nil and pplz[i].Character:FindFirstChild("Torso") ~= nil then 
										
pplz[i].Character.Torso.CFrame = lobby	
end										
end										
end														

At the GiveWep() function, you forgot to clone the gun to the player's backpack, instead you just cloned it to the player.

function GiveWep()
	local a = game.Lighting.Gun:Clone()
	a.Parent = pplz[i].Backpack --This!
end
