On User Input I would like

       Curr_Version_Name and  Curr_Notes 

      to auto populate into a field (while remaining in their current fields) called 

       Notes_History 

      and to add a date/time stamp + a single line space

In that same form I would like 

      any changes On Update of the  Curr_Version_Name and  Curr_Notes 

      to add an entry below the last one in  Notes_History

Been stuck on this one for a while. Would appreciate some help. 

Thanks, guys.
