Get weekly totals grouping records with a letter values

[pinkhamg]

I am brand new to Filemaker. I am having trouble calculating a weekly totals report. I am trying to take 10 groups (a,b,c,d...) and get weekly totals for how many people are classified as a, b, c, etc. at the end of each week. I hope someone can point me in the right direction. Thanks.

You will want to look into subsummary parts and summary fields. They will allow you to create a report that is organized by a sort field with totals, counts, averages, etc.
