Hi. I have a question about if it was possible to control what pages participants go to based off their responses to certain questions? So for instance, I am currently trying to implement a "consent page", where if participants say they consent/agree, they move onto one script that contains the study, but if they hit they don't consent, than instead of immediately aborting the script (which I have now), I want to take them to a new page/script that just has text notifying them that they can't participate in the study, before then terminating. 

Right now I am using the batch element to run all these scripts together, but was wondering if it was possible to lead to different scripts based off what the user responds?  

Thanks!

You don't need yet another script for that. Simply have your consent script do that. I.e. /branch to a trial that displays the "Sorry, you can't participate" message and only then terminate. Everybody else just moves on to the actual task script.
