How do I check for multiple values and if one is not true then it's false?(More in description)

Well there a two ways of doing this. A long way, and a short way. The long way is more specific than the short way.

Here is the short way

local BCV = game.Workspace.CP.BC
local GuestV = game.Workspace.CP.Guest
local TixV = game.Workspace.CP.Tix
local cpl = game.Workspace.CPL

while true do
    wait(1)
        if BC.Value == true and Guest.Value == true and Tix.Value == true then
        cpl.Fire.Enabled = true
            else
            cpl.Fire.Enabled = false
end
end
end

Here is the long way

local BCV = game.Workspace.CP.BC
local GuestV = game.Workspace.CP.Guest
local TixV = game.Workspace.CP.Tix
local cpl = game.Workspace.CPL

while true do
    wait(1)
        if BC.Value == true and Guest.Value == true and Tix.Value == true then
        cpl.Fire.Enabled = true
            elseif  BC.Value == false or Guest.Value == false or Tix.Value == false then
            cpl.Fire.Enabled = false
end
end
end

Hope this helped!
