Crash in my Graphic Interface Settings Program

Hey, so I made a program for changing the background color of my desktop but it keeps crashing,
can you guys help me please ? :)/>

slc = 0
tBarC = 128
tBartC = 1
term.clear()

function drawDesktop()
  term.clear()
  bground = paintutils.loadImage("/DogeOs/Images/settings.nfp")
  paintutils.drawImage(bground,1,1)
  term.setTextColor(colors.black)
  term.setCursorPos(2,3)
  print("Select any color for you background")
  term.setCursorPos(2,11)
  print(" If you want to change your username")
  print(" or your password, simply go to:")
  print(" /DogeOs/API/(username or password)")
  print(" using Finder and follow the instructions")

end

drawDesktop()

      if X >=2 and X <=8 and Y==1 and button ==1 then
      slc = 1

Look at your if, elseif statements. It looks like they are out of order up top.

Line 32:

h = fs.open("/DogeOs/API/color")

"fs.open()" expects you to pass it two strings - the name of the file you wish to open, and the mode in which you wish to open it. You're forgetting the mode.

Try:

h = fs.open("/DogeOs/API/color","w")

Thanks it works perfectly :D/> !

Nice catch. I haven't jumped into the fs Much.
