Conditional Fields Changed Answer Problem I have three fields on an entityform the third is hidden unless the second one is answered with yes. 

The problem I have is that if a user makes three visible by answering "yes" and then answers three but then decided to change question 2 to  "no" field 3 is hidden but the answer is still recorded.
Adding another dependency with field 3 - emptied when question 2 is no should most likely fix your problem
