Millisecond Forums

Hello,

I've been using the same scripts with the same group of participants for 3 years now (it's a longitudinal study with data collection occurring once a year). There are 5 scripts in total, including IATs and more traditional survey questions. About 20 subjects have participated so far and 3 of them have had the same problem with the survey script attached (which is script 4 in the study). For all three, after they get about mid-way through the script to the question about electives the continue button disappears and they cannot continue with the rest of the survey. For 1 of the three it completely froze their computer. The other 2 were able to control-Q to get to the next script but this leaves a lot of missing information. All three tried multiple times on different browsers and kept having the same issue. I've run the script myself and am not able to replicate the issue the select few are having. However, I'd like to prevent this from happening if possible, not only because it frustrates the participants but also results in data loss. Is there something wrong with the script? or might this have to do with something related to their computers?

Thanks!
Carli
