sum ifs on multiple criteria but dynamically moves.

I have a complex formula that i am looking help with. Below is a similar layout.

Shipments
this account 1234 5 5 5
that account 5637 9 9 9
other account 8214 2 2 2

Production
little account 7512 5 5 5
small account 8785 9 9 9
that account 5637 3 3 3
big account 1562 2 2 2

the number of accounts change but sometimes there is the same accounts in both perscriptions and production. i need to dynamically find production and sum the 3 columns for that account. I will need to do the same for each account by title(shipments, production). I cannot add another column as a reference number and i cannot change the account numbers. Also as i said above the number of accounts changes so i cant say something like find production and go 3 cells down or anything like that.

Thanks for any help..
