One of my students got the following error message after completing one of the three IATs. What does it mean?

The message suggests a mistake in the respective script, specifically it indicates tht in <trial instructions> no valid response is defined. A <trial> can only accept "no response" if a timeout or fixed trialduration is specified -- otherwise the <trial> would never end.

If you look at the errors in your logs at https://www.millisecond.com/myaccount/logs/errors.aspx?webscriptid=9856&webscriptname=batchcommand , those suggest that the encoding of your *.iqx files is botched. If you review this very thread, you'll also notice that this isn't the first time this happened with scripts you edited and uploaded. All the errors, including the one depicted in the screenshot, likely stem from this fact. The files are not valid and Inquisit consequently can't parse and execute them properly.

I'd like to know why that is, hence my question: Are you using Inquisit 4 Lab to edit those files or are you using some other application?

Thanks!

Adding a little more information I've been able to glean from the logs: The error referenced in the screenshot occurred with the script "SingleTargetIATBlack.iqx", which was the final script in the condition the respective participant was assigned to. I've pulled all the scripts from the server and the files that are up there currently are encoded just fine and run as expected as far as I can tell. There also isn't any error in the script's instructions <trial>. That may mean that the file was corrupted during the download, which is rare but can happen. Hope this helps.
