My stun system isnt working for combos how can I fix this?

Day 3 of asking for help.

I have made a combat system but the stun is super bad right now when you fire a remote event it fires with the number of seconds you want the target to be stunned but if im doing a combo it puts the stunned value to false and then they can attack again DURING the combo How can I make this more efficient and better??

local script fires the event

Damage:FireServer(hitbox,damage,knockback,stunseconds, punchsfx)

serverscript aka stun/damage script

local gothit = false
game.ReplicatedStorage.Damage1.OnServerEvent:Connect(function(plr, part, damage, knockback, stun, sound)
		local chr = plr.Character
		local hitbox = game:GetService("ReplicatedStorage"):WaitForChild("Hitbox"):Clone()
		local weld = Instance.new("WeldConstraint")
		hitbox.Parent = workspace.Effects
		hitbox.CFrame = part.CFrame
		weld.Parent = hitbox
		weld.Part0 = hitbox
		weld.Part1 = part
		hitbox.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") and hit.Parent.Name ~= plr.Name and hit.Parent:FindFirstChild("Stand") and hit.Parent:FindFirstChild("Hit") and hit.Parent:FindFirstChild("Stand") then
			gothit = true
				local bv = Instance.new("BodyVelocity")
				bv.MaxForce = Vector3.new(1e8,1e8,1e8)
				bv.P = math.huge
				bv.Velocity = chr.HumanoidRootPart.CFrame.lookVector * knockback
				bv.Parent = hit.Parent.HumanoidRootPart
	game.Debris:AddItem(bv,.3)
			hit.Parent.Humanoid:TakeDamage(damage)
			hit.Parent.Hit.Value = true
			hitbox:Destroy()
			wait(stun)
			hit.Parent.Hit.Value = false
			gothit = false
		end
	end)
	wait(0.5)
	if gothit == false then
		if gothit == false then
			hitbox:Destroy()
		end
	end
end)
