So I am trying to create a running total of the "AvgSpend/Month" (which I have displayed as a column in the table below), by Calander[Column 3](Month). I've tried a handful of measures and just can't get anythign to work as intended.
I have a "Calander" table that has a relationship with the current table that I call "Historical."
I intend on this running total meaure to be displayed right next to the AvgSpend/Month on the table below showing the spend at certain points in the year. (The AvgSpend is just an average of 5 years worth of data).
