DAX Calculate / Filter Issue

Hello All,

I have typed up the following Dax formula but the results are not what I am expecting...

Just after a 2nd pair of eyes or someone with a brain to walk me through this.

I have a review form from MS Forms which collates results to questions as per our operational requirements, from there I have pulled it into PBI and the client want to see a COUNT of Yes and No and the % of Yes.

I thought the above DAX would nail it, but for some reason both Yes and No variables are returning the same number (73)

There are 73 rows in the dataset, 71 of which should be Yes and 2 should be No. Any ideas why the variances / CALCULATE function isn't handling as expected? What have I done wrong?
