Subtracting from in variables only subtracts one, How do I fix this?

So, Im making a part that when I click it it subtracts one from a variable. The click detector should work until it hits 0, and I get no errors on this part and it works fine besides for when I click it to subtract.

local clickdetector = game.Workspace["Forest Cavern"].PuzzleOne.ClickDetector

local bricklife = 10

if bricklife > 0 then
	clickdetector.MouseClick:Connect(function()
		local bricklife = bricklife - 1
		print(bricklife)
	end)
end

Heres the code I have written. What happens is, the bricklife starts as ten, then I click it and the bricklife prints 9 in the output, but when I click it again it prints 9 again, and doesnt go down. I clicked it 20 times and it still printed nine, showing its not just something wrong with the print statement. How do I make it so it continually subtracts?

The above answer fixed one problem, the other issue is that you have lines 5 and 6 mixed up.

local bricklife = 10

clickdetector.MouseClick:Connect(function()
	if bricklife > 0 then
		--code
	end
end)
