I have a design with 50 version, 9 concepts and 9 tasks plus one fixed task. I was trying to set up a response file for chip allocation, but Sawtooth gave me a build error saying "The number of responses (11) is not equal to the total number of concepts (including none) for all tasks (90)."
My response file has ID# in the first column, Version# in the second, Task0 (fixed) to Task9 from column 3 to 10. I have 9 rows per respondent (one row per concept), with number of 'chips' as data.
What am I doing wrong?
