Rather than grouping by a week, I need to create groups of 7-day increments. I have a list of patients that sums the amount of treatment time received per day. Then, I need to group these in 7-day increments (and look for how many times they met the 180 minute goal in that period).
The starting date of the treatments is different for each patient, as is the ending date. I have attached an example which demonstrates how I have it now (grouped by week), and how it should look (grouped by 7-day increments). I am new to Crystal, but it seems to me that you should be able to change grouping increment, I just cannot figure out how.
Thanks for your help.
