Job cost report - need guidance

Guys,

Can I get the "total" costs of a job Acutal and Estimated by simply adding all of the "TLE" Material Labor Burden Subcontract fields for "Estimated" and the "TLA" Material Labor Burden Subcontract fields for "Actual" from the JobAsmbl table? Can someone give me an formula for which fields I need to use the JobAsmbl table to add up the Actual and Estimated costs correctly for a job? Thanks in advance!

Mike..
