Hello, so i am trying to make a program where you can turn redstone signals on and off, for controlling various things.

But i am getting this error code

bios:206: [string "control"]:45: '<eof>' expected

Here is a link to the code so you can actually see the problem http://pastebin.com/SbZ7cKeA

I have been trying to fix this issue for about two days now and feel like i could use some help from people that actually know what they are doing.

Thank you.

I don't know anything about elseifs…(Don't facepalm yet)… But I know that when I try to use them, and they fail, I just change then to "if then" and it seems to work out for me.

So i would just change it from

elseif input == "red" then
to
if then input == "red" then

Nope you would want it to be


if input == "red" then

That should be it…I suggest testing it out though…I'm not great with this stuff.

You need to pay more attention to where your 'end's go.

if this == that then
   doThat()
elseif this == theother then
   doTheOther()
else
   WhatDoIDoNow()
end

Notice there's only one 'end', after you've tested all the conditions you're interested in.

I've taken a crack at structuring your code correctly. It's untested, and there seems to be a lot of probably unwanted infinite loops, but I'll leave your logic for you to work out.
