DAX Not Recognising Another Dax

Hi,

I'm just looking for a quick bit of help with a Dax Query. I'm a very basic user of BI so the codes I've used are probably over complicated!

I have the below Dax Query which works fine getting the totals I need:

Sum of Feedback Scores New = IF(SUMX('VTM - Data','VTM - Data'[Does Feedback contain Text?]+'VTM - Data'[Overall Satisfaction Question]+'VTM - Data'[Recommend]+'VTM - Data'[Convenience Question])=0,"",SUMX('VTM - Data','VTM - Data'[Does Feedback contain Text?]+'VTM - Data'[Overall Satisfaction Question]+'VTM - Data'[Recommend]+'VTM - Data'[Convenience Question]))

But I then wanted to create another Dax to simply do a count (so that I can then get a percentage). 

This should work fine (it did in another test but now I can't get it working

SUM of Feedback Received NEW = CALCULATE(COUNT('VTM - Data'[Sum of Feedback Scores New]),FILTER('VTM - Data','VTM - Data'[Sum of Feedback Scores New ]>0))

The issue I now have is the first part of the count, it doesn't recognising the "Sum of Feedback Scores New" column (despite it being a Whole Number valued column.

Once I have it working I wanted to bring the previous calculated measure vs another dax query to get an average:

% Feedback vs Meetings = CALCULATE([SUM of Feedback Received NEW])
/ CALCULATE([No. Of Meetings])

Any help will be greatly appreciated!
