Random Generator Embedded YouTube Videos

Question

Hello,
I would like to ask how should I correctly embed the HTML text to cause the random generator to show one video randomly at a time out of the three.

It is how I am doing right now and I am not sure where to insert the "%random%" command to correctly show the stimulus.

Thank you so much!

Answer 1

Option A (more elegant)

Write the different video URLs into the "Codes (contents)".

Then, in "Display Contents" add the HTML code from YouTube and replace the URL by %random%.

Option B

Write the complete HTML code from YouTube (must be in one line) into the "Codes (contents)".

Only write %random% into "Display Contents".
