Remote Event fires twice despite debounce?

Hi! I started making great progress on my game, and I completed this bomb script, but there's one thing that I haven't experienced ever with remote events. My debounce wont work. I looked at tons of other people and their ways of doing it, but it was exactly like the way I did it. I don't know if this is on the Button scripts end or if its on the Attack scripts end. It creates 2 bombs instead of one, which means double damage! Please help!

This scripts debounce won't work. Server Script, in StarterCharacterScripts.

local part = game.ReplicatedStorage.ClassData.Bloxxer.BloxxerSword:Clone()
local P = script.Parent
local fire = game.ReplicatedStorage.MoveSetFires


local A = P.ATK
local cda = false
local AF = fire.Attack
local A1 = P.AB1
local A1F = fire.AB1
local A2 = P.AB2
local A2F = fire.AB2
local RJ = P.REJ
local RJF = fire.Rejuvinate
local CORE = P.BTZ
local CF = fire.Core

    local Attackcd = false
    local AtCD = .8

A1.Changed:Connect(function(v)
    print(v)
end)

        local function createhitbox(position, size1, size2, size3, damage, tim, offset, plr, ray, direction)
            local hit = Instance.new("Part")
            hit.Size = Vector3.new(size1,size2,size3)
            hit.Color = Color3.new(200,0,0)
            hit.Transparency = .6

            hit.CFrame = position.CFrame
            hit.Orientation = Vector3.new(0, 0, 0)
            hit.CanCollide = false
            hit.Parent = workspace

            if ray == true then

            end

            local destroy = coroutine.create(function()
                wait(tim)
                if hit then
                hit:Destroy()
                end
            end) 
        coroutine.resume(destroy)

            hit.Touched:Connect(function(h)

                if h.Parent ~= plr.Character then
                    if h.Parent.Humanoid then
                        local humanoid = h.Parent.Humanoid or h.Parent:FindFirstChildOfClass("Humanoid")
                        print(h)
                        humanoid.Health = humanoid.Health - damage
                        hit:Destroy()
                end
                end
            end)
        end


            print("okok")
    A1F.OnServerEvent:Connect(function(player)
    wait(.1)
    print(cda)
    if cda == false then    
    cda = true  
        if player then  
    --the hitbox
    local bomb = Instance.new("Part")
    bomb.Name = "Projectile"
    bomb.Shape = Enum.PartType.Ball
    bomb.Color = Color3.new(0,0,0)
    bomb.Size = Vector3.new(1.7, 1.7, 1.7)
    bomb.Transparency = .2
    bomb.CFrame = player.Character.HumanoidRootPart.CFrame
    bomb.Parent = workspace
    --local bv = Instance.new("BodyForce", bomb)

    bomb.CanCollide = false

    bomb.Velocity = player.Character.UpperTorso.CFrame.lookVector * 25
    wait(.1)
    bomb.CanCollide = true
    wait(2)

    createhitbox(bomb, 10.95, 10.95, 10.95, 15, .5, 0, player, false, nil)
    bomb:Destroy()
    --createhitbox(3.1, 2.45, 7.25, 6, .1, -8, player, false, nil)
        cda = false 
        end
    end
end)

This script works and the prints tell me this isn't the problem. Local script, in StarterCharacterScripts.

wait(5)
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local char = player.Character
local mouse = player:GetMouse()
local P = script.Parent
local fire = game.ReplicatedStorage.MoveSetFires


local A1 = P.AB1
local A1F = fire.AB1
local A2 = P.AB2
local A2F = fire.AB2
local RJ = P.REJ
local RJF = fire.Rejuvinate
local CORE = P.BTZ
local CF = fire.Core

local function click(move,cd)
    print(move,cd)
    move:FireServer()
    wait(cd)
end


UserInputService.InputBegan:Connect(function(Input, Gamestuff)
   if Gamestuff then return end
--AB1
    if Input.KeyCode == Enum.KeyCode.Q then
    if A1.Value == false then 

    A1.Value = true
    click(A1F,4)
    A1.Value = false
    end
    end
--Ab2
    if Input.KeyCode == Enum.KeyCode.E then
    if A2.Value == false then

    A2.Value = true
    end
    end
end)
