Connection Minigame

[Jackthemaster]

So I've been working on a little minigame, like those Wire conneting games, we all know 'em, we have all played them. The thing is that mine was doing so good so far and then i saw this:

It's all fine and dandy at first

and then:

This is my code for the energy connection:

[lua] if button[i].OnRight != nil and button[i].OnRight.Powered == true and button[i].Right == true and button[i].OnRight.Left == true then
button[i].PoweredFromRight = true
else
button[i].PoweredFromRight = false
end

if button[i].OnUp != nil and button[i].OnUp.Powered == true and button[i].Up == true and button[i].OnUp.Down == true then
button[i].PoweredFromUp = true
else
button[i].PoweredFromUp = false
end

if button[i].OnDown != nil and button[i].OnDown.Powered == true and button[i].Down == true and button[i].OnDown.Up == true then
button[i].PoweredFromDown = true
else
button[i].PoweredFromDown = false
end

if button[i].PoweredFromLeft or button[i].PoweredFromRight or button[i].PoweredFromUp or button[i].PoweredFromDown then
button[i].Powered = true
elseif button[i].PoweredFromLeft == false and button[i].PoweredFromRight == false and
button[i].PoweredFromUp == false and button[i].PoweredFromDown == false then
button[i].Powered = false
end[/lua]

I know what the problem is but no idea how to solve it. I'm aware it works like 1,2,3. If you cut out 2 then there will be no connection, but if you cut out 1, 2 will think 3 is the power source and vice versa. Help?
