I think it's because the item has no variable name. I tried changing the variable name from "none" to "v1" and it worked fine. Oh, you know why that happens.. because if a "skipto" value matches the variable name, then selecting that option will require you to answer again--it's a way to force a correct response. In this case, the variable name "none" matched all the skipto values for the response options--i.e., "none". Never anticipated that!
