I have two formulas on my report @FromDate and @ToDate. These two dates are the from/to date range for the report. The report always displays a weeks worth of data from the @FromDate (always a Sunday) to the @ToDate (always a Saturday).
If the @ToDate is a known date how can I calculate the @FromDate using the value of @ToDate.
