Thanks you so much for your time - it really is much appreciated!
Just when I thought I figured out an answer to my question, Tableau does not return a value grrrrrrr
Now to my question, on the attached I'm trying to divide my Avg Subscription months (2590) by the number of months selected on my Month filter - in this case I have selected 4 months, so I would expect to see 2590/4 = 647.5 in the Test row. if I selected 5 months the denominator would then be 5.
Can someone take a look at my Test calculation to see while Tableau is returning zero?
You were using [Billing Plan End] in your calculation but your filter is for [Billing Plan Begin]. Changing your calculation to the modified one below, which uses a COUNTD of the DATEPART of the MONTH of [Billing Plan Begin] should get you the number you're looking for. If this is correct, please mark this response as correct. Thx, Don
