Also, is there a better way to do a multiple "group-by"? "Better" is difficult to measure not knowing what other criteria you have. Here is a different solution based on variables instead of keys. Since you don't need a node-set of the groups, you could consider using the solution below. I find using localized variables of only those candidates of a particular group make multi-level subgrouping easier to write and maintain. I hope this helps. .................
