Why am I getting 0 from this array?

Here is the code:

math.randomseed(tick())
 
local t1,t2,t3,t4,t5,t6,t7,t8,t9,t10,t11,t12,t13,t14,t15,t16,t17,t18,t19,t20,t21,t22,t23,t24,t25,t26,t27,t28,t29,t30
CNP = 0
t = CNP
UIP = game.Workspace.UIP
local YourCNP
local rndm1 = math.random()
local rndm2 = math.random()
local rndm3 = math.random()
local rndm4 = math.random()
local UIP = workspace.UIP.Value
 
local rndm11 = math.ceil(rndm1*254)
local rndm22 = math.ceil(rndm2*254)
local rndm33 = math.ceil(rndm3*254)
local rndm44 = math.ceil(rndm4*254)
 
local StaticLocalIP = rndm11.. ".".. rndm22.. ".".. rndm33.. ".".. rndm44

game.Players.PlayerAdded:connect(function(player)
	print(player.Name.. " Has joined and is asigned the following IP: ".. StaticLocalIP)
	
	
	CNP = CNP + 1
	if t==1 then
		t1 = StaticLocalIP
	elseif t==2 then
		t2 = StaticLocalIP
	elseif t==3 then
		t3 = StaticLocalIP
	elseif t==4 then
		t4 = StaticLocalIP
	elseif t==5 then
		t5 = StaticLocalIP
	elseif t==6 then
		t6 = StaticLocalIP
	elseif t==7 then
		t7 = StaticLocalIP
	elseif t==8 then
		t8 = StaticLocalIP
	elseif t==9 then
		t9 = StaticLocalIP
	elseif t==10 then
		t10 = StaticLocalIP
	elseif t==11 then
		t11 = StaticLocalIP
	elseif t==12 then
		t12 = StaticLocalIP
	elseif t==13 then
		t13 = StaticLocalIP
	elseif t==14 then
		t14 = StaticLocalIP
	elseif t==15 then
		t15 = StaticLocalIP
	elseif t==16 then
		t16 = StaticLocalIP
	elseif t==17 then
		t17 = StaticLocalIP
	elseif t==18 then
		t18 = StaticLocalIP
	elseif t==19 then
		t19 = StaticLocalIP
	elseif t==20 then
		t20 = StaticLocalIP
	elseif t==21 then
		t21 = StaticLocalIP
	elseif t==22 then
		t22 = StaticLocalIP
	elseif t==23 then
		t23 = StaticLocalIP
	elseif t==24 then
		t24 = StaticLocalIP
	elseif t==25 then
		t25 = StaticLocalIP
	elseif t==26 then
		t26 = StaticLocalIP
	elseif t==27 then
		t27 = StaticLocalIP
	elseif t==28 then
		t28 = StaticLocalIP
	elseif t==29 then
		t29 = StaticLocalIP
	elseif t==30 then
		t30 = StaticLocalIP
	end
	UIP = {t1,t2,t3,t4,t5,t6,t7,t8,t9,t10,t11,t12,t13,t14,t15,t16,t17,t18,t19,t20,t21,t22,t23,t24,t25,t26,t27,t28,t29,t30}
	local tabl = {t1,t2,t3,t4,t5,t6,t7,t8,t9,t10,t11,t12,t13,t14,t15,t16,t17,t18,t19,t20,t21,t22,t23,t24,t25,t26,t27,t28,t29,t30}
	YourCNP = CNP
	print(#tabl)
end)

game.Players.PlayerRemoving:connect(function(player)
    CNP = CNP - 1
end)

But it just prints 0 from the array, why?
