I'm attempting to embed an online quiz into my Rise course, but I keep getting the error 'Please enter a valid URL or iframe'.
<iframe name="proprofs" id="proprofs" width="100%" height="100%" frameborder=0 marginwidth=0 marginheight=0 src="https://www.proprofs.com/quiz-school/story.php?title=money-mind-set-quiz&id=244857&ew=430">
<div style="font-size:10px; font-family:Arial, Helvetica, sans-serif; text-align:left;"><a href="https://www.proprofs.com/quiz-school/create-a-quiz/" title='Powered by ProProfs' target="_blank" rel="nofollow">Powered by ProProfs</a></div>
Does anyone have any idea why this wouldn't be working?
Any help would be appreciated - thanks!
