Why does this tree chop script not work? (I made it, probably why :P)

local debounce = false
local a = script.Parent      
local b = script.Parent.Log
local c = script.Parent.Log2
local d = script.Parent.Log3
local e = script.Parent.Log4
local f = script.Parent.Leaves
local g = script.Parent.Leaves2
local h = script.Parent.Leaves3
local i = script.Parent.Leaves4
local hits = 0 
local hitsneeded = 4 
b.Touched:connect(function(hit) 
	if not debounce then
		debounce = true
		debounce = false
	  end 
	if hit.Parent.Name == "Basic Axe" then 
		hits = hits + 1 
	
		if hits == hitsneeded then 
			hits = 0 
			b.Anchored = false 
			c.Anchored = false
			d.Anchored = false
			e.Anchored = false
			f.Anchored = false
			g.Anchored = false
			h.Anchored = false
			i.Anchored = false
			f.CanCollide = false
			g.CanCollide = false
			h.CanCollide = false
			i.CanCollide = false
		end
	end
end)

The tree should fall once it reaches 4 hits, but it falls on the first hit which i touch it with the Basic Axe. I was told to add a debounce so I did, still the same thing happens. If I put the "debounce = true" line after the "hits = hits + 1" line, the whole script fails to work and the tree doesn't fall at all. Maybe it's not a problem with the debounce, maybe the script has a problem with the hitsrequired variable and just follows the rest of the script causing the tree to fall?

If you're using a debounce, you wanna make it look something like this:

local debounce = false
local a = script.Parent      
local b = script.Parent.Log
local c = script.Parent.Log2
local d = script.Parent.Log3
local e = script.Parent.Log4
local f = script.Parent.Leaves
local g = script.Parent.Leaves2
local h = script.Parent.Leaves3
local i = script.Parent.Leaves4
local hits = 0 
local hitsneeded = 4 
b.Touched:connect(function(hit) 
    if not debounce then
	    if hit.Parent.Name == "Basic Axe" then
		debounce = true
		hits = hits + 1
	        if hits >= hitsneeded then 
	            hits = 0 
	            b.Anchored = false 
	            c.Anchored = false
	            d.Anchored = false
	            e.Anchored = false
	            f.Anchored = false
	            g.Anchored = false
	            h.Anchored = false
	            i.Anchored = false
	            f.CanCollide = false
	            g.CanCollide = false
	            h.CanCollide = false
	            i.CanCollide = false
	        end
		wait(1) -- You can change this to the time between each axe swing
		debounce = false
	end
    end
end)

I may be wrong, please correct me if I am. Have fun scripting!
