I am a SQL and MS Access whizz and am trying to convert to Filemaker. One of the things I'm struggling with is calculating YTD sales by store and product category. The table I have has sales listed by store, product category, and week ending date. What I want is to create a report that summarizes the YTD sales by store and product category and I have no idea how to do this. In Access it would be a simple summary by store and product category. Any help would be appreciated for this Filemaker newbie. Thanks.
