C4 Function just doesn't work... And it's so basic! Why???

So I'm making a C4 and everything works, EXCEPT for the detonation and re-equip, which I'm working on.

Anyway, I'm completely baffled at how this script actually ignores itself. I first used a variable called "Flipped" and it would equal false at the top of the script. That clearly wasn't working, so I tried putting a boolean value inside the script and it reacted the same way!! What do I do? Am I just making a stupid mistake without realizing it?

Here's the function:

--Top of script
Flipped = false

function Detonate()
    if not Flipped then
        --Right here would have the animation, which I'm still working on
        Tool.Handle.PlantA:Play()
        print(tostring(Flipped))
        Flipped = true
        print(tostring(Flipped))
    elseif Flipped then
        --Complex explosion... Could be the problem... But it keeps printing "false true, false true" and it's making the sound. But it never says "true false, true false"
        for i,v in pairs(C4Folder:GetChildren()) do
            if v.Name == Player.userId.."_C4" then
                v.Name = Player.userId.."_C4_DETONATE"
                v.C4Blink.BrickColor = BrickColor.new("Really red")
                v.C4Blink.Beep:Play()
                delay(v.C4Blink.Beep.TimeLength, function()
                    local explode = Instance.new("Explosion", workspace)
                    explode.BlastRadius = script.ExplodeRadius.Value
                    explode.Position = v.C4.Position
                    local sound = Instance.new("Sound", v.C4)
                    sound.SoundId = "rbxassetid://142070127"
                    sound.Volume = 1
                    sound.Pitch = 1
                    sound:Play()
                    game.Debris:AddItem(v, 3)
                    explode.Hit:connect(function(hit)
                        local Hit_Player = game.Players:GetPlayerFromCharacter(Hit.Parent) or game.Players:GetPlayerFromCharacter(Hit.Parent.Parent)
                        if Hit_Player == nil or not script.AntiTK.Value or (Hit_Player ~= nil and not (not Hit_Player.Neutral and Hit_Player.TeamColor == Player.TeamColor)) then
                            local Humanoid = hit.Parent:FindFirstChild(human)
                            if not Humanoid then --Not there...
                                Humanoid = hit.Parent.Parent:FindFirstChild(human)
                                if not Humanoid then --Didn't hit a gun? Maybe it didn't hit a character at all!
                                    return
                                end
                            end
                            if Humanoid == nil or not Humanoid then
                                return
                            end
                            for i,v in pairs(Humanoid:GetChildren()) do
                                if v.Name == "creator" then
                                    if v.Value == Player then
                                        v:Destroy()
                                    end
                                end
                            end
                            local c = Instance.new("ObjectValue")
                            c.Name = "creator"
                            c.Value = Player
                            game.Debris:AddItem(c, 5)
                            c.Parent = Humanoid
                            delay(0, function()
                                if hit then
                                    hit.Visible = true
                                    wait(script.ReloadTickSpeed.Value)
                                    hit.Visible = false
                                end
                            end)
                        end
                        if Hit_Player ~= nil and script.AntiTK.Value then
                            if Hit_Player.TeamColor == Player.TeamColor then
                                explode.BlastPressure = 0
                            end
                        end
                    end)
                end)
            end
        end
        print(tostring(Flipped))
        Flipped = true
        print(tostring(Flipped))
    end
end

I've been constantly looking over this and just can't figure it out! Do I just need to redo this function? Or am I just being completely ignorant and not seeing the simple mistake right in front of me?
