I have a report from a user input query that lists the data and has it broken down into three "tiers" or subcategories. The last tier contains 4 fields, one of which is a numerical value. On the report built from the query, at the top of the third tier I use the =Sum function to give me a total qty of the numerical values in that tier. My new problem is I find that I need to additionally get a sum value of all of those sum values in the tier above that. Is there an easy way to perform a Sum(SumX) type function?
