Cumulative Total

ElliotP Sorry about the original post. It was from my phone and had typos :smileywink:

Okay here is the formula for Running Total as a Calculated Column (prorerly formatted)

Running Total COLUMN =
CALCULATE (
    SUM ( 'All Web Site Data (2)'[UniquePageviews] ),
    ALL ( 'All Web Site Data (2)' ),
    'All Web Site Data (2)'[Date] <= EARLIER ( 'All Web Site Data (2)'[Date] )
)

And as you can see it works! :smileyhappy:

And here's the MEASURE formula

Running Total MEASURE = 
CALCULATE (
    SUM ( 'All Web Site Data (2)'[UniquePageviews] ),
    FILTER (
        ALL ( 'All Web Site Data (2)' ),
        'All Web Site Data (2)'[Date] <= MAX ( 'All Web Site Data (2)'[Date] )
    )
)

Which also works...
