Confused why roblox output is saying "expected (to close 'function' at line 15) near '<eof>'"?

Code :

   --- MADE BY C7SN --- 

--- VAIRBLES ---
local Part = script.Parent -- this is the Part we will move
local newPos = Part.Position + Vector3.new(82.55, 19.96, 59.85) -- the position the Part will go to
local Time = 10 -- the time that the script will take to move the part
local Increment = 0.5 -- the Part will move 0.5 studs each time it moves
local Debounce = false
local Diff = newPos - Part.Position -- the difference between the two positions
local Mag = Diff.magnitude -- the distance between the two parts
local Direction = CFrame.new(Part.Position, newPos).lookVector

--- FUNCTION ---
workspace.Part.Touched:connect(function(otherPart)
	function MovePart() -- function to move the Part
 	if Debounce then return end -- end the function if debounce is true
	Debounce = true -- make Debounce true so the function can't run
	for n = 0, Mag, Increment do
		Part.CFrame = Part.CFrame + (Direction * Increment)
		wait( (Time/Mag) * Increment )
	
	end
	Debounce = false -- set Debounce to false so the function can run again
	end
	
workspace.Button.ClickDetector.MouseClick:connect(otherPart)

That other function inside the event isn't needed. And you forgot a ')'

end)

workspace.Button.ClickDetector.MouseClick:connect(otherPart)

You simply needed a parenthesis and another end (you might have found this if you indented properly), and simply means "end of file", or just near the end of the script. So, all you need another end with a closing parenthesis.

Hope this helps!
