I get a half pyramid of data, like this, all the way down for about 150 
entries. What I want, of course, is a single column of unique cost 
center entries, with page count totals for each. But, at least I'm 
getting something. Thanks for your help, Alex. I'll keep you abreast of 
any progress.
{"ADAM00"=>8}
{"CBCD00"=>8, "ADAM00"=>8}
{"CBCD00"=>8, "EDDG00"=>8, "ADAM00"=>8}
{"CBCD00"=>8, "EDDG00"=>8, "JOSH00"=>4, "ADAM00"=>8}
{"CBCD00"=>8, "EDDG00"=>8, "JOSH00"=>4, "ADAM00"=>8, "HCCG00"=>4} . . .
