Average with Two Filters Return Blank

[jbax70]

Hi guys. 

How come the formula I use keeps returning blank?

Sunny and Stormy = CALCULATE(AVERAGE(delivery_statistics[Time Taken 2]),FILTER('delivery_statistics','delivery_statistics'[Type_of_vehicle]= "Sunny"&&'delivery_statistics'[Weatherconditions] = "Stormy"))

You need to use or ( || ) instead of and ( && ). Also, you're checking the wrong column for Sunny.
