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?
