I have a construction co that I have set up a workbook for each project. The workbook contains a project database foe each individual project. Within that database, a summary page shows billings, costs, etc. i would like one sheet to compile or summarize all the workbooks - in other words, have a summary sheet that totals all the jobs (individual workbooks). So my yearly sales and costs are always at my fingertips with one summary sheet totalling all the individual summary sheets.
