This is what I DID:
I created an inline section, housing a multiple choice question; with conditional questioning off of each of the choices.

This is what I EXPECTED to happen:
I expected that if you selected yes, you'd be conditioned correctly, and if you selected no after selecting yes, the original multiple choice would reset, therefor not showing the conditionally visible text box from the second choice.

This is what DID happen:
Well, see. I'll explain it this way.

I have it setup as conditional questioning;

"Do you have a domain?" Multiple Choice. "Yes," "No,"
"Yes," conditions "Which domain?"
"No," Conditions "Would you like us to purchase one for you?" As a multiple choice question.

The "Would you like us to purchase one for you?" multiple choice, is again, another set of multiple choice questions, sanctioned off by conditional questioning.

"Yes," conditions "Which domain were you interested in?"
"No," Doesn't do anything.

Now, for instance.

I select at the beginning that I don't have a domain. It drops to the second row of conditions, I select yes and it goes to the third, ...

I go back, and select that I already have a domain, and it now overlaps the other responses (still active in background,) and gives you the reply, for the other answer.

You can see what I did, I guess. It's in "Contact Us!" in my forms.
