So.. I'm having a lot of trouble with animations, works in one place but doesn't in another?

It works with other models, it works in other places also owned by me. But it doesn't work in the place I want it to work, same weapon, same scripts, and same animations used. Equip Script:

wait(0.1)
local tool = script.Parent -- use local variables
local Player = game.Players.LocalPlayer --get the local player
local isitEquipped = Player.hasWeapon
local getName = Player.Name
local attack = workspace:FindFirstChild(getName).Humanoid:LoadAnimation(script.equipAnimation)

tool.Equipped:Connect(function(mouse) -- :Connect not :connect, :connect is deprecated
	isitEquipped.Value = true
	attack:Play()
	attack.KeyframeReached:Connect(function(keyframeName)
    	if keyframeName == "Pause" then
        attack:AdjustSpeed(0)
    end
end)
end)

tool.Unequipped:connect(function()
	isitEquipped.Value = false
	local idle = workspace:FindFirstChild(getName).Humanoid:LoadAnimation(script.Idle)
	attack:AdjustSpeed(1)
	wait(0.1)
	attack:Stop()
end)

Attack Script:

wait(0.1)
local tool = script.Parent
local Player = game.Players.LocalPlayer --get the local player
local Mouse = Player:GetMouse() --get the mouse
local isitEquipped = Player.hasWeapon
local cooldown = 0
local onCooldown = false
local canDamage = false
local critChance

function onClick ()
	if isitEquipped.Value == true and script.Parent.Parent.ClassName == "Model" and cooldown == 0 then
		local attack = tool.Parent.Humanoid:LoadAnimation(script.Attack) -- script.Parent is tool so just use tool.Parent
		attack:Play()
		attack:AdjustSpeed(script.Parent.itemSpeed.Value)
		print("clicked")
		cooldown = 1/script.Parent.itemSpeed.Value
		wait(1/script.Parent.itemSpeed.Value)
		cooldown = 0
	end
end

function damageEnemy (enemy)
	if cooldown ~= 0 then
		if not canDamage then
			canDamage = true
			if enemy.Parent:FindFirstChild("Monster") then
				critChance = math.random(1,100)
				if critChance <= script.Parent.itemCritical.Value then
					enemy.Parent.Monster:TakeDamage(script.Parent.itemCritDamage.Value*script.Parent.itemDamage.Value)
				else
					enemy.Parent.Monster:TakeDamage(script.Parent.itemDamage.Value)
				end
				wait(script.Parent.itemSpeed.Value)
			elseif enemy.Parent:FindFirstChild("Humanoid") and enemy.Parent.Pvp then
				if enemy.Parent.Pvp.Value == true then
					critChance = math.random(1,100)
					if critChance <= script.Parent.itemCritical.Value then
						enemy.Parent.Humanoid:TakeDamage(script.Parent.itemCritDamage.Value*script.Parent.itemDamage.Value)
					else
						enemy.Parent.Humanoid:TakeDamage(script.Parent.itemDamage.Value)
					end
					wait(script.Parent.itemSpeed.Value)
				end
			end
			canDamage = false
		end
	end
end

Mouse.Button1Down:connect(onClick)
script.Parent.Part.Touched:connect(damageEnemy)

Is there a way to convert the animations to script since it is so demn complicated --'
