Code:

local zm = 'zmienne'
term.clear()
term.setCursorPos(1,1)
print "Status Wlaczania: "
if fs.exists(zm) then
  term.setCursorPos(1,2)
  print "Zmienne [X]"
 else
  term.setCursorPos(1,2)
  print "Zmienne [ ]"
  fs.open(zm, "w")
  fs.close(zm)
  term.setCursorPos(1,2)
  sleep(1)
  term.clearLine()
  print "Zmienne [X]"
end

Error:
startup:12: attempt to call nil

zmienne is in polish in english it means variables />

fs.open returns a file handle, which is what needs passed to close, not the file name.

local h = fs.open(zm, "w")
h.close()

Maybe try this:

local zm = 'zmienne'
term.clear()
term.setCursorPos(1,1)
print "Status Wlaczania: "
if fs.exists(zm) then
  term.setCursorPos(1,2)
  print "Zmienne [X]"
else
  term.setCursorPos(1,2)
  print "Zmienne [ ]"
  fs.open(zm, "w")
  fs.close()
  term.setCursorPos(1,2)
  sleep(1)
  term.clearLine()
  print "Zmienne [X]"
end

Tell me if that's what you wanted.

OK but when i'm editing file "zmienne" and if i'm click any button it's writing

edit:363: bad argument: string expected, got nil

Maybe try this:

That is still the same incorrect usage of fs.close. See my above post.

[mibac138]

This dont work...

[dissy]

My code is tested and verified, and it works.
If you are getting an error, we need to see both the error and the code to help.

[mibac138]

Maybe give me yours code

[dissy]

My code was

h = fs.open("newfile", "w")
h.close()

It creates the new file, closes the file handle, and no errors.

Is the file in rom? If it is, you can't delete it

Post the current version of the code, incorporating the repair suggested by dissy, and the error message for that version. Don't tell us you've got new error messages without posting the code that produced them.
