I think I broke my GUI

Ok, so I'm working on a door program to open doors when I click on a screen. I have made something like this before, and it worked okay, but that was with a lot more tables and code, since it was more complicated. The problem I am having with my code is that the color states of the diagram on the left, as well as the alarm on the roght do not change when I click them. I know that the states are changing because the status is updated on the right, but it won't update the diagram on the left.
can someone tell my why it's broken?

local shutterState = false
local entranceState = false
local processingState = false
local alarmState = false
local x,y = term.getSize()
local statusLights = {
 shutter = {
  light = {"[--------------]"},

  BGcolor = shutterState and colors.red or colors.lime,
  action = function()
	if shutterState then
	 shutterState = false
	 rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.white)
	else
	 shutterState = true
	 rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") + colors.white)
	end
   end,
  x1 = 5,
  x2 = 20,
  y1 = 2,
  y2 = 2},

  light = {"[url="file://\\====/"]\\====/[/url]"},

	 entranceState = false
	 rs.setBundledOutput("bottom", rs.getBundledOutput("bottom") - colors.white)

Looks like you need to update BGColor in your action() function.

And how exactly would I do that?

When you call v.action() just change the colour of v.BGcolor right then.

if events[3] >= v.x1 and events[3] <= v.x2 and events[4] >= v.y1 and events[4] <= v.y2 then
    v.action()
    v.BGcolor = v.BGcolor == colours.lime and colours.red or colours.lime -- you should know how this works, just does the opposite of what it currently is
    drawGUI()
end

probably change v.action() to v:action()
change the action = function() parts to action = function(self)
and then do
self.BGColor = processingState and colors.red or colors.lime
and such

Well, it came close…..but not quite.
All that did was change all of the colors……to the opposite. and each time i click, it changes color to all of them :I

EDIT: Nevermind. I had the call in the wrong place.
