I want the report to contain information only about last three days and the difference in sales between
1. today and yesterday
2. today and day before or
3. yesterday and day before
3 answers

Here is what I want to do:
Q1. At (1) I want a column which gives the difference between subtotals for 28th and 29th of nov.
At (2) I want another column which gives the difference between subtotals for 28th and 30th of nov.
Q2. Is it possible to only show details of current date and last two dates? Like here I have to select the dates on my own or it shows all days.
Q3. Can the data for 30th be seen first. Latest data in the first column i mean.
Thanks
