can you provide a step by step for pulling in a table item, adding three columns, and getting the group by the one column for the remaining two?

For me the steps went like this:

-added table item

-first column division_name

-second column sent_leads

-third column referrals

-add sum to both sent_leads and referrals

-highlighted both sent_leads and referrals, right clicked, added parent group on division_name

I've attached result. I need the sent_leads to sum up to 1002 for Central, and 337 for East....a true roll up. I've attached image of what I'm getting.

Can someone tell me where in my steps I missed something?
