Dear Support,
Nothing worked, unfortunately. 
I am trying to insert the HTML code to the answers. My experiment is as follows:
• 35 tasks + Intro + Demographics
• 3 audio files per task (105 audio files total)
• Participants listen to all three recordings as many times as they want.
• They choose one of the three recordings.
• The order of the 35 tasks should be randomized.
• The positions of the three audio files within each task should also be randomized
How do I do this?
I need to attach three different audio files to each answer A, B, and C.
I can not drag them from the library. They are all downloaded there, and when I try adding the code nothing happens.
The files are named 01A, 01B, 01C ..... 35A, 35B, 35C
The task shall look like this:
TASK-1 The sound of a small stone hitting the ground
(Das Geräusch eines kleinen Steins, der auf den Boden trifft) :
A. (audio button) B. (audio button) C. (audio button)
Thank you,
Maria
