Updating workbook formulas for additional variables

Hi nickpavlov,

I did some changes, now you can use the TRACKBACK again and for the date question I offer the solution of choosing instead the starting date of the Data table and the Today's date as limits that you can choose in the drop down menu, those dates do not limit the entry of other dates, it is just for not using blank as a criteria.

I also changed the order of the first two columns to their original places.
