Survey calculate percentage of one question/answer set using 2 dimensions

[RogerG]

Hello all, I have this script and am trying to calculate the % of an answer based on the question

data:
LOAD * INLINE [
    Choose your Functional Group, How long?, The purpose is clear, How likely is it that you would recommend tool?
    F1, 0-6 months, Agree, 1
    F1, 6 months-1 year, Strongly Agree, 3
    F2, 0-6 months, Disagree, 4
    F2, More than 1 year, Strongly Disagree, 6
    F3, 0-6 months, Aggee, 10
    F3, 6 months-1 year, Neutral, 6
];



DataLoad:
CrossTable(Question, Answer)
LOAD [Choose your Functional Group] as Function,
	[How long?],
	[The purpose is clear],
	[How likely is it that you would recommend tool?]
Resident data;



Duration:
LOAD * INLINE [
    DurationSortOrder,AnswerDuration
    1,More than 1 year
	2,0-6 months
	3,6 months-1 year
];

drop table data;
exit script;

from this, I tried several dimensions and expressions

Dimension to get a specific question

D1  =if(Match(AnswerDuration,Answer),Answer)

D2 - Function

However to calculate the duration percent for that question, I get the wrong answers

E1 - count(if(Match(AnswerDuration,Answer),Answer)) / count(total<Question,Answer>if(Match(AnswerDuration,Answer),Answer))

then I tried (Idea is to count total, filtering on both question and answer)

count(if(Match(AnswerDuration,Answer),Answer)) / count(total<if(Question={'How Long?'},Question),if(Match(AnswerDuration,Answer),Answer)>if(Match(AnswerDuration,Answer),Answer))

I can't seem to get the correct answers for this problem

TIA
