Why does it display this error?

Hello everyone! :)

I am very happy that I just made a meltdown detector script. But I have a problem, it displays

Workspace.FanButton.FanButton1.Script:19: '' expected near 'end'

in the error console. Why?

The script works fine. Nothing is broken. It is when I added >= it displays this error. Before I had == 1000

Can someone please tell me what is causing this error? :p Thanks.

ReactorMeltdownSong=game.Workspace.ReactorMeltdownSong

FanProtector2=game.Workspace.FanProtector.Image2
FanProtector3=game.Workspace.FanProtector.Image3
FanProtector4=game.Workspace.FanProtector.Image4

FanStatus5=game.Workspace.FanStatus.FanStatus5.Decal
FanProtector=game.Workspace.FanProtector

while true do
	wait()
if Temperature.Value >= 1000 then
    Temperature.Value = 1001	
    FanProtector.Transparency = 1
    FanProtector.CanCollide = true
	FanProtector1.Texture = ''
	FanProtector2.Texture = ''
	FanProtector3.Texture = ''
	FanProtector4.Texture = ''
	FanProtector5.Texture = ''
	FanStatus1.Texture = 'http://www.roblox.com/asset/?id=163640412'
	FanStatus2.Texture = 'http://www.roblox.com/asset/?id=163640412'
	FanStatus3.Texture = 'http://www.roblox.com/asset/?id=163640412'
	FanStatus4.Texture = 'http://www.roblox.com/asset/?id=163640412'
	FanStatus5.Texture = 'http://www.roblox.com/asset/?id=163640412'
	ReactorSafeguards:Play()
	wait(2)
	ReactorMeltdownSong:Play()
	wait(4)
	ReactorSafeguards:Play()
end
end

I just ran this script and am not getting this syntax error (I hadn't seen anything wrong in the syntax)

Try restarting studio and trying again.

EDIT: Actually, maybe you pasted here the wrong script. The error sounds like there should be an end near to line 19, however there isn't. Also check that you actually looking at the right script (FanButton1's Script)

Style note: You should tab your code properly!
