Hi! 
I have this type of situation -
Qa16 "What have you used" (Multiple choice)
Online stores
Price comparison
Booking
None

Qa19 "Write in websites in each category" (Array (Texts))
Online stores (3 text boxes)
Price comparison (3 text boxes)
Booking (3 text boxes)


I would need the Qa19 to only give write in options to respondent if he has selected them in Qa16. I understand I can't get this done by conditions. I found this topic -  forums.limesurvey.org/forum/can-i-do-thi...-in-a-later-question ; putting {Qa16_SQ001.shown}; {Qa16_SQ002.shown} etc. in Qa19 gives something closer to what i want, but the answer text boxes are still there and only the label disappears. 
What should I use here?
Thank you! 

Please read the manual, it's full of good stuff.

Thank you! For some reason I wanted to make simple thing a lot harder.
