Spreadsheet That Keeps Track Of Data From Other Workbooks?

User will save as Job # or Job name to their computer This job # or Job name will be also typed in location ..lets say cell a2 of every workbook the user creates from the master workbook. After the user is finished inputting all data into workbook they save it when they save it to send or have another workbook pull from it certain information...lets say total hours and total $$ respectively in cells s30 and p18

this workbook will save those numbers every time the user opens the one he is working on and saves it(could the workbook be closed and still store these data figures from other workbooks)

workbook called "DATA STORAGE" will compile this information from every workbook created from the original master workbook.

The point is so that the user can instead of opening up a possible 50 to 60 workbooks to check on $$$$ and hours they can see that information from all 50 or 60 workbooks at once on one page.
