Hahaha i had the same problem when i tried to learn how to embed videos. ohkae so well anda go to the "embed a video" button, anda will see it if anda answer atau ask a question. so it will say copy the url. so anda go back to your video, click the share button below the video nd then copy the url. it will jusst look like a whole bunch of letters nd numbers. then anda go back to your soalan nd paste it. thats pretty much it
