reshowing a trial if there is an error as opposed to continuing down the timeline

[csavasegal]

Does anyone have any suggestion for how to reshow the same trial after displaying an alert (as opposed to proceeding to the next one?) Right now I get an alert appropriately, but the timeline continues to the next trial without letting someone fill in the missing input that they got the alert for. I have a sense that I need to add another procedure that potentially loops through the current one, but have not been able to do so successfully. Many thanks in advance!

Have you considered the "required" attribute?

Example
<input name="first" type="text" required>

Thanks!
