Calculating total dollars and percentages by job

spreadsheet.jpg

I am setting up spreadsheet for our Quality Department which needs to know total dollar and percentage of non-conformance's by department and by job #. I have by department set up and done however I'm having issues figuring out what formula to use for job #. The smaller chart on the left is what I need filled in. I need to select all of one job from column A and add up their totals in column g to fill column n (total $) and repeat for column 0 (total %). Note that one job may have 3 issues while another job may have 6 and the next may only have 1 issue.
