[TYPO3-english] Rules-based survey

[Sergey Alexandrov]

Guys,

I'm trying to find rules or answer- based survey extension. I mean, survey "flow" depends on already answered questions. The simplest one should "recognize" yes/no and depending on answer display different set of questions, which could be yes/no as well and so on... Just wondering if such ext exists 

Thank you,
Sergey
