First of all, love this plugin. Probably the best premium plugin out there with the friendliest user interface. I do have a slight problem though with it at this page -- http://avenuek9.com/contact/
Specifically, when you select the last radio button ("I have a question about your site"), which brings up another (conditional) question ("Is this a troubleshooting/technical issue?"), then select an answer (Yes/No) *AND THEN* go back to select a different answer up top (eg. "I work for a PR firm and there's this cool thing I want to talk to you about."), the child questions based off of the Yes/No question *DO NOT* disappear.
If this still sounds a bit unclear, you can replicate the issue by first selecting the 3rd radio option/answer from the top on the first question, then the 2nd radio option/answer from the top on the second question, and then changing the answer on the first question -- it'll still display the options from the second question below. Just wondering if that's a GF glitch or if it can't handle nested conditional questions.
Any help is much appreciated!
