    Hi Caz_16 ,

    If you want to calculate the cases between current week and last week which based on current week, you can try this measure:

    Change by week =
VAR _Week =
    WEEKNUM ( TODAY (), 2 )
VAR thisweeknumber =
    CALCULATE (
        SUM ( 'VDH-COVID-19-PublicUseDataset-Cases'[Total Cases] ),
        'VDH-COVID-19-PublicUseDataset-Cases'[Week Number] = _Week
    )
VAR lastweeknumber =
    CALCULATE (
        SUM ( 'VDH-COVID-19-PublicUseDataset-Cases'[Total Cases] ),
        'VDH-COVID-19-PublicUseDataset-Cases'[Week Number] = _Week - 1
    )
RETURN
    thisweeknumber - lastweeknumber

     

    Based on your dataset, it will get the result like this:

yeah, contexts are hard.

 

Try to save the current week number into a variable BEFORE you start with Calculate.
