Problem calculating production rate

Philippe,

My mistake, try the below. I just added Production[Date] to the SUMMARIZE function.

Production Rate (Measure) = 
VAR MinutesProduced = SUM ( Production[MinutesProduced] )
VAR MinutesOpen =
SUMX (
    SUMMARIZE ( Production, Production[EmployeeID], Production[Date], Production[Minutes opened] ),
    Production[Minutes opened]
)
VAR Result =
DIVIDE (
    MinutesProduced,
    MinutesOpen
)

RETURN Result

This is what mine looks like now:
