Why doesn't this decal script work? [STILL UNANSWERED]

Hi, my script is highlighting line 5. I know why but I don't know how to fix it. I just had a holiday for a week so it has removed all of my knowledge of scripting. Please help me fix this simple error.

I think else has to do something with the 'if' statement. I just can't remember though -_-

Best regards, Nathan.

Fanfive=game.Workspace.Fans.Five.Decal

function onClick()
	Fanfive.Texture = 'http://www.roblox.com/asset/?id=166126631'
else
	Fanfive.Texture = 'http://www.roblox.com/asset/?id=166126649'
end

script.Parent.ClickDetector.MouseClick:connect(onClick)

Where you have the else I think it should be 'else if'

You were probably right about the 'if' statement

Hope this helps.

^Ignore above^

I think it should be like this

Fanfive=game.Workspace.Fans.Five.Decal

function onClick()
    Fanfive.Texture = 'http://www.roblox.com/asset/?id=166126631'
else)
    Fanfive.Texture = 'http://www.roblox.com/asset/?id=166126649'
end

script.Parent.ClickDetector.MouseClick:connect(onClick)

whys there a else when there is no if?
