 Which is exactly what this will do.  When you ask for help, you might want 
to try what people suggest.  If you had tried what Chris suggested (twice!) 
you would have discovered that his suggestion solves the problem you have 
described.  Please respect the time and effort of volunteers answering 
questions in this forum.  You can do this best by devoting some time and 
effort to thinking about and learning from the responses posted.  At least 
try a suggested solution before complaining that it doesn't work!
