How do I avoid an error regarding modules in ReplicatedStorage?

Hello,

I developed a terrain generating script, and have decided first to implement organizing the regeneration/ degeneration of the terrain by functions, and putting them into ReplicatedStorage, where my main script can reference it. When I ran my game, I had found out that the lag had reduced by a lot. I was planning to test out another optimization script, but I got an error: 20:33:15.746 - ReplicatedStorage.Generation:64: '}' expected (to close '{' at line 2) near 'print' 20:33:15.747 - Requested module experienced an error while loading

Below is the code in ReplicatedStorage, the script called Generation. Following that is the main script in my Workspace that I used to put the functions together:

return 
{
Speed = 5, -- Keep between 1 and 5
Generate = function(Self)
--set block count
local howManyClones= 0

--create a group called "DirtBlockCloneGroup"
local dirtBlockCloneModel= Instance.new("Model",game.Workspace)
dirtBlockCloneModel.Name= "DirtBlockCloneGroup"

	for timer= 1,0,-1 do --timer that counts from 3/ any # to 0 by seconds
		wait(1)
		print(timer)
	
			if timer== 0 then
				print("Done.")--ends timer, then does action below
			end--end if
	end--end for
		
x0= game.Workspace.DirtBlock.Position.X
y0= game.Workspace.DirtBlock.Position.Y
z0= game.Workspace.DirtBlock.Position.Z
--sets whatever position the original dirt block is in, stores in variables
local original= Vector3.new(x0,y0,z0)

local zIncr= 3 --increments new clone blocks by changing z coordinate
--line below checks and gets testing plate size
local zSizeBase= game.Workspace.BasePlate.Size.Z
local zSizeCheck= 3--baseplate comparison, so clone won't pass plate boundaries

local xSizeBase= game.Workspace.BasePlate.Size.Z
local xSizeCheck= 3
local xIncr= 3

	for i= 1,4 do--sets how many layers of bricks
		
		for i= 1,(xSizeBase/3) do-- because it increments by 3 studs
			
			while zSizeCheck<zSizeBase do
				clone= game.Workspace.DirtBlock:Clone()-- creates clone
				clone.Name= "DirtBlockClone" -- changes name of dirt block
				clone.Parent= game.Workspace.DirtBlockCloneGroup --adds the instance into the Workspace
				clone.Position= Vector3.new(x0,y0,z0-zIncr)
				clone.BrickColor= BrickColor.new("Black")
				howManyClones= howManyClones+1--cloned brick counter
		
				zIncr= zIncr+3-- ex. 3 away from original, 6 away, 9 away etc.
				zSizeCheck= zSizeCheck+3
			end
		
		zSizeCheck= 0--these scripts reset the position, so it won't shift
		zIncr= 0
		x0= x0+3
		wait(0)--delay to minimize lag, edit between dev and release
		end
	
	end	
	
	y0= y0+3-- goes to the next level, 3 studs up
	x0= game.Workspace.DirtBlock.Position.X-- resets at original point
	end
	
print(howManyClones)--prints the number of bricks

end,--end function generate

Degenerate= function(Self)
	wait(0)
	game.Workspace.DirtBlockCloneGroup:Destroy()
	wait(0)
end--end function Degenerate

}--end of return at very beginning

local Generation= require(game.ReplicatedStorage.Generation)

while true do
	
--create terrain
Generation:Generate()-- or regenerate

--allow player to play buy freeing them from spawn area
game.Workspace.SpawnArea.SpawnBaseBottom.CanCollide= false
game.Workspace.SpawnArea.SpawnBaseBottom.Transparency= 1

--this period is the playing time before the map resets
	for timeToReset= 100,0,-1 do
		wait(1)
		test2= Instance.new("Hint",game.Workspace)
		test2.Text= "Map reset and respawn deactivation in: "..tostring(timeToReset)
	end--end for

--players go back when map is regenerating
game.Workspace.SpawnArea.SpawnBaseBottom.CanCollide= true
game.Workspace.SpawnArea.SpawnBaseBottom.Transparency= 0.75

target= CFrame.new(60.5,3358,84.5)
for i, player in ipairs(game.Players:GetChildren()) do
	if player.Character and player.Character:FindFirstChild("Torso") then
		player.Character.Torso.CFrame= target+ Vector3.new(i*2,0,0)
	end
end

--clear terrain
Generation:Degenerate()

end

One of my attempts was to follow exactly what the message had said and put a brace after the indicated line:

	end	
	
	y0= y0+3-- goes to the next level, 3 studs up
	x0= game.Workspace.DirtBlock.Position.X-- resets at original point
	end
	
print(howManyClones)--prints the number of bricks}

end,--end function generate

Degenerate= function(Self)
	wait(0)
	game.Workspace.DirtBlockCloneGroup:Destroy()
	wait(0)
end--end function Degenerate

}--end of return at very beginning

The only other option I had was to avoid ReplicatedStorage and put all the code into a single, main script in the workspace.

Edit: The pre-class object in the code was supposed to be normal text; below it was the attempted script.
