What's a good general, validation-approach to enforce a different response pattern for each row in a matrix?
A have a multiple-choice matrix question that includes four columns and six statements (six rows). Respondents are asked to select exactly two columns in each row while not repeating their selection pattern across the rows. For example, if for Row 1 they choose Columns 1 and 2, they should not choose those same two columns on any other row. If they do, they should receive a validation error message. I've tried to implement this with custom validation. But so far, the rules appear to be too complex for custom validation to handle. Any ideas about what direction I should go in, to try to solve this problem?
