Use letter to calculate data

Hi Experts.  Attached is the spreadsheet that needs an expert to add the missing part to it.   The spreadsheet has two sections (top and bottom).  The top section is where all of the information is manually entered that relates to customer information.  The first column is where I would like to enter a B if the line relates to information for a business.  The bottom of the spreadsheet is where I would like to have all of the business information summarized from the top (lines that have a B only).  I don't know how to calculate this based on a B being in the column.  Help.

Thanks for the help experts! FixMe.xlsx
