I have a question where I need some help.
I have a CRF with 5 questions. If the answer to question 1 is "yes" then you must answer questions 2 and 3 but questions 4 and 5 may not contain any data. Likewise if the answer to question1 = "No" the question 4 and 5 must be answered and question 3 and 4 must contain data.
Initial data is simple using the SHOW/HIDE option but if the data has to be changed then this option with SHOW/HIDE does not work!
Anyone with a smart idea??
