Whats wrong with this program?

So basically when i run this program it returns "bit:40: bad argument : double expected, got nil"
I thought it ment i had 2 of the same colors but i don't.
If you want to see what the program is for go to my other topic: TOPIC
Heres the code

mon=peripheral.wrap("back")
mon.clear()
mon.setCursorPos(1,1)
mon.setTextScale(3)
print"Coal Generators: "
print"Geothermal Generators: "
print"Wind Mills: "
print"Water Mills: "
print"Solar Panels: "
print"HV Solar Arrays: "
print"MV Solar Arrays: "
print"LV Solar Arrays: "
while true do
	mon.setCursorPos(1,1)
	mon.setTextScale(3)
	os.pullEvent("redstone")
	local rsnpt = rs.getBundledInput("right")
	print("Coal Generators:"..(colors.test(rsnpt,colors.grey) and " On" or " Off"))
	print("Geothermal Generators: "..(colors.test(rsnpt,colors.pink) and " On" or " Off"))
	print("Wind Mills: "..(colors.test(rsnpt,colors.lime) and " On" or " Off"))
	print("Water Mills: "..(colors.test(rsnpt,colors.yellow) and " On" or " Off"))
	print("Solar Panels: "..(colors.test(rsnpt,colors.cyan) and " On" or " Off"))
	print("HV Solar Arrays: "..(colors.test(rsnpt,colors.magenta) and " On" or " Off"))
	print("MV Solar Arrays: "..(colors.test(rsnpt,colors.orange) and " On" or " Off"))
	print("LV Solar Arrays: "..(colors.test(rsnpt,colors.white) and " On" or " Off"))
end

(update) I have tried all different colours so its not that.
(update) I have copied it into pastebin for you guys http://pastebin.com/isUZgV40

Update
Just did it with different colors and had no luck still

ummm, I don't see why you only have
os.pullEvent("redstone") alone,
atleast add

while true do
	    mon.setCursorPos(1,1)
	    mon.setTextScale(3)
	    local sEvent = os.pullEvent("redstone")
	    if (sEvent == "redstone") then
	    local rsnpt = rs.getBundledInput("right")
	    print("Coal Generators:"..(colors.test(rsnpt,colors.grey) and " On" or " Off"))
	    print("Geothermal Generators: "..(colors.test(rsnpt,colors.pink) and " On" or " Off"))
	    print("Wind Mills: "..(colors.test(rsnpt,colors.lime) and " On" or " Off"))
	    print("Water Mills: "..(colors.test(rsnpt,colors.yellow) and " On" or " Off"))
	    print("Solar Panels: "..(colors.test(rsnpt,colors.cyan) and " On" or " Off"))
	    print("HV Solar Arrays: "..(colors.test(rsnpt,colors.magenta) and " On" or " Off"))
	    print("MV Solar Arrays: "..(colors.test(rsnpt,colors.orange) and " On" or " Off"))
	    print("LV Solar Arrays: "..(colors.test(rsnpt,colors.white) and " On" or " Off"))
	    end
end

That's just me though

If it pulls the event of redstone, that is the only event, why bother checking it, he is just waiting for a redstone signal

I'm writting some code for you that will update automatically.

Im sorry but I am a littlee busy today… I will post the code latter on.

EDIT: I have the code but I see you worked it… Nevermind

colors.grey is nil. The value you want is colors.gray (with an "a") or colours.grey (British spelling).

Its actually more of 'stupid Americans', if they didn't decide they couldn't speak the same english as the rest of the world, the whole world would use 'colours.grey'

I make the colors.grey mistake all the time, and I don't even use bundled cable…like, ever. So I'm pretty conscious of it.

yeh I make it heaps too, I can never remember which is American and which is British spelling. and the Sublime Text 2 plugin that GravityScore made doesn't help either. he needs to add the conditions :P/>

I have coded it but I see you worked it out… Nevermind

I al still very interested in your code for my main computer at spawn on my server.

Here is the code I would use… The only way to leave the program is to hold CTRL + R… It will update when a redstone inout updates.. YOu can change the scale and the background color. Sorry for the wait.

[spoiler]

local monitor = peripheral.wrap("left")
term.redirect(monitor)
monitor.setTextScale(1)
local m1 = "Coal Generator: "
local m2 = "Geothermal Generators: "
local m3 = "Wind Mills: "
local m4 = "Water Mills: "
local m5 = "Solar Panels: "
local m6 = "HV Solar Arrays: "
local m7 = "MV Solar Arrays: "
local m8 = "LV Solar Arrays: "
local ONLINE = "ONLINE"
while true do
term.setBackgroundColor(colors.blue)
term.setCursorPos(1, 1)
term.clear()
rsin = rs.getBundledInput("right")
print()
print("			  GENERATOR	  STATUS")
print()
print("		 " .. m1 .. "    " .. (colors.test(rsin, colors.gray) and ONLINE or "OFFLINE"))
print("  " .. m2 .. "    " .. (colors.test(rsin, colors.pink) and ONLINE or "OFFLINE"))
print("			 " .. m3 .. "    " .. (colors.test(rsin, colors.lime) and ONLINE or "OFFLINE"))
print("		    " .. m4 .. "    " .. (colors.test(rsin, colors.yellow) and ONLINE or "OFFLINE"))
print("		   " .. m5 .. "    " .. (colors.test(rsin, colors.cyan) and ONLINE or "OFFLINE"))
print("	    " .. m6 .. "    " .. (colors.test(rsin, colors.magenta) and ONLINE or "OFFLINE"))
print("	    " .. m7 .. "    " .. (colors.test(rsin, colors.orange) and ONLINE or "OFFLINE"))
print("	    " .. m8 .. "    " .. (colors.test(rsin, colors.white) and ONLINE or "OFFLINE"))
os.pullEvent("redstone")
end

(I tested it)

Wow! I'm going to copy this into pastebin now and use it at spawn! Thankyou very much!!! :)/>
