Time Duration-Dependent Skipto? (case 3134)

[gdurso]

Hi--

I am trying to piggyback a short study onto another. The problem is that we only want people to be able to take the study if there is sufficient time left in the session for participants to take it.

I was thinking that this could be accomplished via a complex skip using responses.xls, if it can record the amount of time that people take to go from the second screen to the last screen. But, I am unsure how to actually do it.

So, ideally, my study would be presented to Ps only if they take < 18 min to complete the initial study. Is there a way to program this rule?

I am trying to get this coded and ready for Monday morning at 8am, as the materials are time-sensitive (we are measuring political attitudes and voting intentions ahead of the Tuesday election). Any immediate advice would be extremely welcome and appreciated.

Thanks much for your help,
