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
