"it doesn't work

How doesn't it work? Show us the error messages (verbatim, please) and the warnings, if any. Provide a narrative description of how output is different than your desire.

Help us to help you.

Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
  1. code
  2. verbatim error and/or warning messages
  3. a coherent explanation of what "doesn't work actually means.

How do I post a question effectively?
