i have a workbook that contains two sheets.

Sheet one contains a list of names. Each name references an information
sheet for that name. I wish to collect data for each name for a specified
number of days "x". When that number of days is met, then I wish to click on
a button on the toolbar to delete some number "x" of days of data from 1 -
"x" including "x". I wish to do this to make the data more current hence
meaningful
