We are having problems insuring that participants are seeing every item within a questionnaire. For example, participants will only see items/screens 1-6 in a questionnaire that has 12 items. After item #6, the program jumps to the next questionnaire (without alerting participants or experimenters that they have missed something). We can't see anything within the experiment editor that would indicate why this is happening. It also seems to happen randomly (i.e. always within the same questionnaire, but not always within the same condition or experiment). Help?
