I have survey questions that can change by number at anytime. when the each question has a noted response that is given a special ID.
after all responses have been gathered for a given survey, the grouping starts over at 0.. I want each grouping, no matter how many surveys, to have a unique id for each grouping see below and would be dynamic if/when additional surveys were added with their own questions.
example...
grouping by question should be
0 response id 100
0 100
0 100
1 response id 101
1 101
1 101
0 new survey response id 200
0 200
0 200
1 201
1 201
1 201
2 202
