Error with friend's code I never had and dont understand?

I'm trying to fix a code for a friend, but it says "statement spans multiple lines, as an error" Also the speed changer won't work. I have no idea what to do, i've never had these errors before

Please help my friend

Script:

function Launch(char, target, speed)  
char.Torso.BodyPosition.position = target.Position
print("Loop started.  Target brick: " .. target.Name)
while char.Parent ~= nil do
	if (target.Position - char.Torso.Position).magnitude < 20 then
		print("Player at target")
		return
	else
		print((target.Position-char.Torso.Position).unit*speed)
		char.Torso.BodyPosition.maxForce = Vector3.new(
		500*math.abs(((target.Position - char.Torso.Position).unit*speed).x), 
		100*math.abs(((target.Position - char.Torso.Position).unit*speed).y),
		500*math.abs(((target.Position - char.Torso.Position).unit*speed).z))
		char.Torso.BodyGyro.cframe = CFrame.new(char.Torso.Position, char.Torso.Position+char.Torso.Velocity)
	end
wait(0.1)
end
end

function MakeWeightless(m)
	local p = m:getChildren()
	for i = 1, #p do
		if p[i].className == "Part" or p[i].className == "Seat" then
		local g = Instance.new("BodyForce")
		g.force = Vector3.new(0, p[i]:getMass()*196.2, 0)
		g.Parent = p[i]
		elseif p[i].className == "Model" or p[i].className == "Hat" then
		MakeWeightless(p[i])
		end
	end
end

function RemoveWeightless(m)
	local p = m:getChildren()
	for i = 1, #p do
		if p[i].className == "Part" or p[i].className == "Seat" then
		local g = p[i]:findFirstChild("BodyForce")
		if g ~= nil then g:remove() end
		elseif p[i].className == "Model" or p[i].className == "Hat" then
		RemoveWeightless(p[i])
		end
	end
end

function onTouched(part)
local players = game.Players:getChildren()
for i = 1, #players do
	if players[i]:findFirstChild("Launched") == nil and players[i].Character ~= nil then
	if players[i].Character:IsAncestorOf(part) then
		local h = players[i].Character:findFirstChild("Humanoid")
		if h.Health ~= 0 then
		if players[i].Character:findFirstChild("Torso") ~= nil then

bp.P = 10000
bp.D = 5000
bp.Parent = h.Parent.Torso
bp.maxForce = Vector3.new(0, 0, 0)


local point = game.Workspace.locationz1

Launch(players[i].Character, point, speed)


local point = game.Workspace.locationz2
local speed = 1000
Launch(players[i].Character, point, speed)

local point = game.Workspace.locationz3
