Below is the table and data I am using to illustrate.
Each person with Unique ID have 2 choices.
Only 1 choice will be offered. And each person has to indicate whether to accept the choice allocated to him/her.
What is the expression to count the number of person who have accepted 'Butter, as their choice? (ie Acceptance = 'Yes' and ((1st Choice = 'Butter' and ChoiceOffered = '1st') or (2ndChoice = 'Butter' and ChoiceOffered = '2nd'))
