Good afternoon.
I am new to QV and especially on this page, I have learned enough of sowftware because I read a basic tutorial, but in my work I need to make running means ingeniarmelas and I can not, I give you an example.
If I select November 2011, December 2011, Jan 2012 - I want a column in the table shows me the total sales of these selected periods, and the next column shows me the total sales of the periods 1 years leater, in this case i need to show me the total of sales of November 2010, December 2010, Jan 2011.
How can i write a code for this problem?
Thank you for your help.
