Previous Period using Calendar

[Anonymous]

I have a simple formula that worked in another file but doesn't seem to work in my current one. The same formula works in one workbook but not the other and im scratching my head on why it isn't working.

PY $ = VAR Previous = SELECTEDVALUE('Date Table'[Calendar YearWeekNumber])-1
RETURN
CALCULATE(
    [Gross Sales],
    'Date Table'[Calendar YearWeekNumber]=Previous)

Hi @Anonymous,
I reviewed the BI report. What happend over there is used two different columns in your model, used Calendar Year column to the visual and Calendar YearNumber for DAX logic. Because of that your getting BLANK values in the visual. You can refer below snippets and make sure that both visual fields and DAX logic columns should be same.

Thanks,
