I am having a problem with 2 of 7 machines. I have several questionnaires that employ the RWG and skipto commands to assign between-subjects conditions. This works on 5 of my machines. That is, participants are only seeing one of three sets of stimulus materials. However, on two of the machines, participants see the stimuli 3 times. It appears that the RWG function is working because it is a random sequence of the three stimulus materials but I think the skipto command is not working on these machines. All 7 machines are actually accessing the same experiment and questionnaire files on the server, so they all are receiving the same input info but 2 are behaving very differently. I have tried “repairing” the program under add and remove programs. But, I haven’t yet tried uninstalling and re-installing MediaLab. Do you have any suggestions?
