Help with Advanced monitors and touchschreen

Hello there. I've been wondering around how to make a computer with advanced monitor attached to its TOP to respond on a touchschreen click on a specific location. I've made a script which prints a red-outlined button on a white background ( on a 2 by 2 grid of advanced monitors ) with the text "Touch Me!" and when the button is pressed, it gets an orange background (only in the place where there is text) The problem is where i have the if statement ( look in the program ), because it kinda ignores all the y axis of the touch. Aka i touch anywhere below the text and it still thinks the button is pressed. Any suggestions of improving the script, so the if statement thinks the button is pressed then the x axis is anywhere between 1 and 9 and the y is 1? Thanks for the time you spend reading my propably stupid question…

I am running an OLD version of computercraft (Minecraft 1.4.7) With Feed The Beast Ultimate modpack if that is in any attention

Yeah, using a bunch of or statements is a pretty inefficent and redundant way of doing it. Using greater than and less than makes it much easier.

while true do
event, side, xPos, yPos = os.pullEvent("monitor_touch")
  if yPos==1
  and xPos >= 1 and xPos <= 9 then
	press()
	unpress()
  end
end

Though if you really wish to use and in combination with or, you'd add parenthese like this.

while true do
event, side, xPos, yPos = os.pullEvent("monitor_touch")
  if yPos==1 and (xPos==1 or xPos==2 or xPos==3 or xPos==4 or xPos==5 or xPos==6 or xPos==7 or xPos==8 or xPos==9) then
	press()
	unpress()
  end
end

As you can see here: http://www.lua.org/m...nual.html#2.5.6 and has a higher precedence than an or.

So you actually have to make brackets in your if-statement. Should look like this:

if yPos==1 and (xPos==1 or xPos==2 or xPos==3 or xPos==4 or xPos==5 or xPos==6 or xPos==7 or xPos==8 or xPos==9) then

Also it'd be easier to do the following:

if yPos == 1 and xPos >= 1 and xPos <= 9 then

Thanks very much! I dodnt know that. I tried to do like i=1,9 adn if xPos==i, but that didnt work as expected.
