**# A text box where you enter a retention string in format '''retainVal=NNN retainUnit=XXXX''' where NNN is a number from 1 to 3 digits long, and XXX is a time unit likee.g. "days"second, minute, hour, day, week, month, quarter, or year.

** Because the updates are so frequent this database table grows very quickly, and you need to say when it should delete the older rows so the table never has too many rows. If you think about it, after a few days, you probably do not need to look at this very detailed level of values information within a day. In that case set retention to delete after a few days ''retainVal=3 retainUnit=daysday''.
