hello all.
I need help.
I have a date.
I suppose you select a day, for example, February 7, 2011.
I have to calculate:
Sales of the Day Calculator icon
sales since the beginning of the month (from 01 February 2011-07 February 2011)
sales since the beginning of the year (from January 1, 2011 to February 7, 2011)
sales reported for the same period the previous year, however, both a monthly and annual basis.
I thank you in anticpo and I wish all a happy and prosperous new year.
Francesco
