my sword doesnt moves at all, thats the code:

local debounce = false
local ragdoll = require(game.ServerScriptService.Ragdoll)
local function attack(plr)
    for i,v in pairs(workspace:GetChildren()) do
        if v.Name ~= plr.Character.Name then
            if v:FindFirstChild("Humanoid") then
                if (plr.Character.Torso.Position - v.Torso.Position).Magnitude < 15 then
                    if not v:FindFirstChild("counter") then
                            local huumanE = v.Humanoid
                            huumanE:TakeDamage(7)
                            local hit = Instance.new("BoolValue",v)
                            hit.Name = "Hit"
                            huumanE.WalkSpeed = 1
                            game.Debris:AddItem(hit,1)
                            return v
