Grandfather, I appreciate the help on going about substituting the old values for the new values. I didn't figure out I could use a hash. I was having a blockage. Your code captured the task I wanted to get done. I now have to do this for 100's of records. I will also read your tutorial on databases (SQLlite) before attempting to clean up my code and show the updates here. I may have more questions coming when using the SQL database to write up my code. Thanks, Perlynewby
