Fix issues with Tableau sheet tracking

The goal of the attached Tableau workbook is to count the number of active drivers for a program. Each driver has an ID number, a start date and an end date and these are listed as discrete events in a table, along with a time for each event. The workbook is already partially constructed, but it has several issues that need addressing/troubleshooting: 1) On the 'Driver Growth Chart' and 'Driver Growth Chart by Plan' the Y axis should reflect a COUNT of the total active drivers. Currently it shows a very high value, perhaps a SUM of the driver IDs? 2) The 'Driver Chart' sheet shows 'Joins,' 'Quits,' 'Net Change,' and 'Total Active,' which should be the the difference between the prior month's total active figure and the net change for the current month. While the other values are displaying correctly, the 'Net Change' is not - this needs to be corrected. This was working at one point but stopped working when some items were moved around to get the row labels added. These row labels (or something similar) must remain. 3) Create a second driver table (similar to 'Driver Chart' that provides joins and quits by plan. I.E. For 'Household' Joins Quits Net Change Total Active For 'Campus' Joins Quits Net Change Total Active Chart should automatically populate with new plans if they are added. Please review the workbook before submitting a bid for this project.
