Mein Skript :

shell.run("clear")
term.setCursorPos(7,3)

term.setCursorPos(25,10)
print(" :D/>")
term.setCursorPos(7,13)
sleep(5)
print("Now you …")

sleep(10)
shell.run("clear")
print("If you …")

password = read()

if password == ("Lock") then true
print("lock is …")
sleep(2)
shell.run("clear")
shell.run("ONIX")

elseif password == ("Help") then true

elseif password == ("Animation") then true

eof=true

Well first off use code tags when posting code

[ code] --no space
-- enter code here

–no space


Second, you should use term.clear() instead of shell.run("clear"). I'd imagine it'd be faster for the computer and to type out.

Third your if and elseif statements have 'true' after 'then'. This has nothing to do with that boolean. It should look like

password = read()
if password == "help" then
return "help"
elseif password == "animation" then
return "animation"
else
return "yo dawg.  your password is all wrong"
end

edit: also should mention that you have an elseif statement after your else, which is why you're erroring. put that last elseif before the else.
