Great question because I don't think it's clearly enough emphasized in the manual that the d (duration) parameter needs to go in the experiment (.exp) file rather than in the questionnaire (.que) file. Basically you can do a countdown for a que but currently not for a single item within it.

So..! here is what you can try and hopefully it will work for you..

I know some people don't use .exp files to organize their experiments--are you familiar with them? If so, try adding (d-60) as a parameter where you list this particular questionnaire in the .exp file. If you have only one item in the questionnaire, it's functionally equivalent to adding a countdown timer to a single item. The other benefit though is that you have the option to include a timer that spans multiple items within a single questionnaire (e.g., such as a time limited recall test and such). Hope that helps and let me know if you have any trouble with it.
