2. delete these lines that begin with the pair name. I don't use them anymore (you probably use an old template, from v1). Good line names are: onesixth, twosixth, threesixth, foursixth and fivesixth. If you still get pair+xxxsixth name, you are using an old SIXTH indicator. Use the most recent version.
3. can't do nothing for this one. This error is returned by MT4.
