How to Set Up a Timer in MediaLab

Hi All ,

I am using MediaLab to set up a research study using questionnaires. I've read the manual and it seems that I could specify a duration time in the parameter box and specially used a negative duration time to get a timer (e.g., d-300). I've tried this but it did not work.

What I would like is to set up a timer for each section of the questionnaires (e.g., 5 minutes for the first 5 questions and another 4 minutes for the second set of 5 questions). And most importantly, the screen would directly go to the next section when time is up. A timer allows participants to better allocate their response time throughout each section.

Can someone help me with this? I understand there are other posts out there talking about timer, but I am still confused about where did it got wrong.

Thank you very much.
