showif %contains% with previous survey

[Michal Hužva]

As part of the run in survey, I want to use "showif" to show only some items based on the previous answers in the previous survey. Using previous_survey$answer %contains% "answer" doesn't work. I can't use == because it's a string of many characters. How else can I display fields in current survey based on values in previous survey?

thanks for advice or providing sources on that

Your approach should work. In what way does it not work? Please send a reproducible example and try to clearly explain the goal.
