My mining tool only seems to work for 1 ore, yet both have the same code?

I have two ores: Gold Ore and Iron ore. The parts are exactly the same except for the color and the name.

Inside the parts: Script #2 Damage Needed(Value) Damage(Value)

In the picax:

local Damage = 0
------------------------------
local MiningSound = script.Parent.MiningSound
local MinedSound = script.Parent.MinedSound
------------------------------
function reset()
DamageNeeded = 0
Damage = 0	
end
---------------------------------------
script.Parent.Handle.Touched:connect(function(basePart)
	if (basePart.Name == "IronOre") then 
		local player = game.Players:FindFirstChild(script.Parent.Parent.Name)
		local ironore = game.ReplicatedStorage.UnrefinedIronOre:Clone()
		if (player) then
			DamageNeeded = basePart.DamageNeeded.Value
			Damage = Damage+1
			MiningSound:Play()
			
			if Damage >= DamageNeeded then
				ironore.Parent = player.Backpack
				MinedSound:Play()
				basePart.Name = "CannotMineIronOre"
				basePart.Transparency = 1
				basePart.CanCollide = false
				wait(10)
				reset()
				basePart.Name = "IronOre"
				basePart.Transparency = 0
				basePart.CanCollide = true
			end	
	-----------------------------------------------------------
	if (basePart.Name == "GoldOre") then 
		local player = game.Players:FindFirstChild(script.Parent.Parent.Name)
		local goldore = game.ReplicatedStorage.UnrefinedGoldOre:Clone()
		if (player) then
			DamageNeeded = basePart.DamageNeeded.Value
			Damage = Damage+1
			MiningSound:Play()
			
			if Damage >= DamageNeeded then
				goldore.Parent = player.Backpack
				MinedSound:Play()
				basePart.Name = "CannotMineGoldOre"
				basePart.Transparency = 1
				basePart.CanCollide = false
				wait(10)
				reset()
				basePart.Name = "GoldOre"
				basePart.Transparency = 0
				basePart.CanCollide = true
			end	
		end
	end
	return (nil);
	
		end
	end
	end)

In the Gold Ore:
hits = script.Parent.Damage.Value
hitsneeded = script.Parent.DamageNeeded.Value
function onTouch(hit)
	if hit.Parent.Name == "RustyPicax" then
		hits = hits+1
		script.Parent.Mine:Play()
		wait(0.5)
	end
	if hits > hitsneeded then
		script.Parent.CanCollide = false
		script.Parent.Transparency = 1
		print "GoldOreMined"
		
	end
end

script.Parent.Touched:connect(onTouch)

When the picaxe touches a part, if it is Iron ore or Gold ore it is supposed to increase the hits by 1 until it is >= to the hits needed.

Mining Iron Ore Works fine, Gold doesn't do a thing. Why does Iron work and not gold?

I don’t think you can define the value of an intvalue in a variable, try taking value out and then adding it to whenever you call the variable. Hope that works for you.
