Please don't hijack the thread.  People who use threaded mail readers
will have difficulty following or finding your question.

Assuming you used the script from the prior thread, I had no problem

The error itself suggests that something is masking objects like
optimize.portfolio in your .GlobalEnv, but without more information
there's nothing to diagnose.
