Reset parts of worksheet automatically, but not others

First, ignore the colored portions. This is how I kept track of what I had completed in the form as I created it. Clients attend class once a week and would be marked present on the corresponding day of class. This increases column #3 "classes attended" to "1". What I would like is for my individual classes sheet to reset every Monday (as the date of the report on top) but for the "5groups" worksheet to keep count of the classes attended. Does that make sense? Please, any imput would REALLY be appreciated.
