Cumulative change by quarter using ProductX of measure?

Hello, I have a measure calculating the quarter on quarter unit price changes (call it Measure1). I now want to make another measure (Measure2) that multiplies (1+ values of Measure1) in all quarters up to the selected quarter. Sample data below:

Year-QuarterUnit Price (Measure1)Measure2 (output)
2022 Q1-1+0% = 100%
2022 Q230%(100%)*(1+30%) = 130%
2022 Q315%(100%)*(130%)*(1+15%) = 149.5%

 

Measure2 = 
// Variable for (1+Measure1) value 
VAR _n = IF(ISNUMBER('Calculations'[Unit Price]), 'Calculations'[Unit Price] + 1)

RETURN CALCULATE(PRODUCTX( 
     FILTER( ALLSELECTED('Date'[DecimalDate]), 
          'Date'[DecimalDate] <= SELECTEDVALUE('Date'[DecimalDate]) ), 
     _n) )

 

My returns Measure2 output is ridiculously large numbers. Snapshot hereI cropped out the row names but each row represents a different supplier. My data starts at 2019 Q3 so Measure 2 should equal (Unit Price + 1) for that quarter. Everything after that should be a product building off of it. But you can see some funky numbers (eg row 2).

You can't really put SELECTEDVALUE into a CALCULATE.  Use variables instead.
