Help on preventing count on a blank cell

[jonbox]

Hi, I currently have the below metric which counts the number of rows containing 1 and shows as a percentage, e.g. if there are 31 rows and 16 contain 1, the measure will count that there are 31 and say 52% of the rows contain 1. 

My only issue with this is i don't want the measure to tally empty rows:

Dpt:	Score:
Hair	1
Beauty	0
Skincare	1
Products
Face	1

The above example should return 75% as it only counts the 1's and 0's, calculating the number of 1's from the count.

The blank cell for products is not counted. How can i reflect this in the below measure?

Dec % Per Dpt =

DIVIDE(

CALCULATE( COUNTROWS('Dept Scorecard 2122'), 'Dept Scorecard 2122'[Dec_6] = 1 ), 

CALCULATE( COUNTROWS('Dept Scorecard 2122'), ALL('Dept Scorecard 2122'[Dec_6] )

))

@jonbox , try a measure like

Dec % Per Dpt =
DIVIDE(
CALCULATE( COUNTROWS('Dept Scorecard 2122'), 'Dept Scorecard 2122'[Dec_6] = 1 ),
CALCULATE( COUNTROWS('Dept Scorecard 2122'), Filter(ALL('Dept Scorecard 2122'[Dec_6] ), not(isblank('Dept Scorecard 2122'[Dec_6]))
)))
