Why won't my script work? [ANSWERED]

So, I just made this but it doesn't work!

Please can someone tell me!

function onClicked()
	local h = Instance.new("Message")
	h.Parent = game.Workspace
	h.Text = "Attention!"
	wait(5)
	h.Text = "Self Destruct Activated!"
	wait(5)
	h.Text = "You have two minutes to evacuate!"-----You can adjust time if you wish but make sure you remove any extra wait command thingies
	wait(5)
	h.Text = "90 Seconds!"
	local s = Instance.new("Smoke")----- This creates smoke simply for the effect!
	s.Parent = game.Workspace.SDS.SBrick1----- You can add more smoke scripts by making new bricks and copying this line with new bricks name!
	wait(5)
	h.Text = "60 Seconds!"
	wait(5)
	h.Text = "45 Seconds!"
	wait(5)
	h.Text = "30 Seconds!"
	wait(5)
	h.Text = "15 Seconds!"
	wait(5)
	h.Text = "10 Seconds!"
	wait(5)
	h.Text = "5 Seconds!"
	wait(5)
	h.Text = "Initiating Self Destruct!"
	wait(5)
	s.Remove()
	local e = Instance.new("Explosion")
	e.Parent = game.Workspace.SDS.EBrick1
	e.Remove()
	wait(5)
	local e = Instance.new("Explosion")
	e.Parent = game.Workspace.SDS.EBrick1
	e.Remove()
	wait(5)
	local e = Instance.new("Explosion")
	e.Parent = game.Workspace.SDS.EBrick1
	e.Remove()
	wait(5)
	h.Remove()
end
script.Parent.SelfD.MouseClick:connect(onClicked)

Best regards, Nathan

The error is simple, you put . when you were supposed to put a : The script corrected & simplified

script.Parent.SelfD.MouseClick:connect(function ()
	local h = Instance.new("Message",game.Workspace)
	h.Text = "Attention!"
	wait(5)
	h.Text = "Self Destruct Activated!"
	wait(5)
	h.Text = "You have two minutes to evacuate!"
	wait(5)
	h.Text = "90 Seconds!"
	local s = Instance.new("Smoke",game.Workspace.SDS.SBrick1)
	wait(5)
	h.Text = "60 Seconds!"
	wait(5)
	h.Text = "45 Seconds!"
	wait(5)
	h.Text = "30 Seconds!"
	wait(5)
	h.Text = "15 Seconds!"
	wait(5)
	h.Text = "10 Seconds!"
	wait(5)
	h.Text = "5 Seconds!"
	wait(5)
	h.Text = "Initiating Self Destruct!"
	wait(5)
	s:Remove()
	local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)
	e:Remove() -- You should put a "wait()" before this so the explosion doesn't auto remove when created  ~tyopido
	wait(5)
	local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)
	e:Remove() -- Same as line 28 ~tyopido
	wait(5)
	local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)
	e:Remove() -- Same as line 28 ~tyopido
	wait(5)
	h:Remove()
end)

Because script.Parent.SelfD.MouseClick:connect(function ()

02 local h = Instance.new("Message",game.Workspace)

03 h.Text = "Attention!"

04 wait(5)

05 h.Text = "Self Destruct Activated!"

06 wait(5)

07 h.Text = "You have two minutes to evacuate!"

08 wait(5)

09 h.Text = "90 Seconds!"

10 local s = Instance.new("Smoke",game.Workspace.SDS.SBrick1)

11 wait(5)

12 h.Text = "60 Seconds!"

13 wait(5)

14 h.Text = "45 Seconds!"

15 wait(5)

16 h.Text = "30 Seconds!"

17 wait(5)

18 h.Text = "15 Seconds!"

19 wait(5)

20 h.Text = "10 Seconds!"

21 wait(5)

22 h.Text = "5 Seconds!"

23 wait(5)

24 h.Text = "Initiating Self Destruct!"

25 wait(5)

26 s:Remove()

27 local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)

28 e:Remove() -- You should put a "wait()" before this so the explosion doesn't auto remove when created ~tyopido

29 wait(5)

30 local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)

31 e:Remove() -- Same as line 28 ~tyopido

32 wait(5)

33 local e = Instance.new("Explosion",game.Workspace.SDS.EBrick1)

34 e:Remove() -- Same as line 28 ~tyopido

35 wait(5)

36 h:Remove()

37 end)
