The only way I know how to do this, would be to use the Summary platform to aggregate the statistics, and then to use the Split platform to create different columns for the Direct and Trade data and then to create new columns to sum the counts and to concatenate the 2 Channels. Finally, you can then take the modified data table and use the Tabulate platform to display the results.
Thank you Jim! I'm stuck in the split step you mentioned- how did we get the direct trade in the right place to concatenate while having the numbers in the cells?
