Enemy NPC not doing damage. Does this have something to do with debounce?

I pretty the problem is in the basicAttack function at line 41. The canDamage value only changes if hit.Parent.Humanoid.IsBlocking.Value == false and hit.Parent.Humanoid.NPC.Value == false. If the hit thing is blocking or is a npc then the rest of the code isn't allowed to be run which stops the canDamage from being set to true. So basically move the canDamage outside of the if statements as seen below.

local damageWeapon = script.Parent.Parent.Damage -- .Value(!)
local canBeDisarmed = script.Parent.Parent.CanBeDisarmed
local bladeWeapon = script.Parent
local optionalTouchPartWeapon = script.Parent.Parent.Pole
local wielderHead = script.Parent.Parent.Parent.Head

local basicAttackAnim = script.Parent.Parent.Parent.Attack
local basicAttackAnimPlay = script.Parent.Parent.Parent.Humanoid:LoadAnimation(basicAttackAnim)
local attacking = false
--local touched = false
local canDamage = script.Parent.Parent.CanDamage

local function warnAttack()
    wielderHead.AttackUI.SwordIcon.Visible = true
    wielderHead.AttackUI.SwordIcon.ImageColor3 = Color3.fromRGB(255,0,0)
    wait(0.2)
end

local function basicAttack()
    --print(canDamage.Value)
    basicAttackAnimPlay:Play()
wait(basicAttackAnimPlay.Length)
    wielderHead.AttackUI.SwordIcon.ImageColor3 = Color3.fromRGB(0,255,0)
--  wait (math.randomseed(3,5))

optionalTouchPartWeapon.Touched:Connect(function(hit)
        if canDamage.Value == true then
        canDamage.Value = false
        --  print("attacking")
        --if touched == false then
        --touched = true

        if hit.Parent:FindFirstChild("Humanoid") then
        --  if attacking == false then
            --  attacking = true
                if hit.Parent.Humanoid.IsBlocking.Value == false then
                    if hit.Parent.Humanoid.NPC.Value == false then 
                    hit.Parent.Humanoid:TakeDamage(damageWeapon.Value)
                    bladeWeapon.HitSound:Play()

                    --{ wait(2) Take From Here
                    --  canDamage.Value = true
                     -- if target is blocking     

                    elseif hit.Parent.Humanoid.NPC.Value == false 
                    and hit.Parent.Humanoid.IsBlocking.Value == true  then

                    bladeWeapon.BlockSound:Play()
                    bladeWeapon.Sparkles.Enabled = true
                wait(0.2)
                    bladeWeapon.Sparkles.Enabled = false
                        wielderHead.AttackUI.SwordIcon.ImageColor3 = Color3.fromRGB(0,255,0)
                wait(1)
                        wielderHead.AttackUI.SwordIcon.Visible = false

                    --elseif not hit.Parent:FindFirstChild("Humanoid") then
                    --  canDamage.Value = true

                    --else
                    --canDamage.Value = true
                end
            end
        end
    end
    end)
    wait(2) --And Put here
    canDamage.Value = true
end

while wait(0.5) do
    if script.Parent.Parent.Parent.EnemyInSight.Value == true then
repeat
wait(2)
    warnAttack()
    basicAttack()
until  script.Parent.Parent.Parent.EnemyInSight.Value == false
        wielderHead.AttackUI.SwordIcon.Visible = false
    end
end

Alright, lassies and gents - I may have found the solution. I'm not sure what I did, but I'll post the script down below, only problem I currently have with it is that it doesn't register when the player is blocking. Thank you all for your replies (I'm very grateful for that), any more help would be greatly appreciated
