The audio control panel simply does not show. On this website I should see the control panel. http://www.testplek.annemariebeeke.nl/huiswerkopdracht_week3_bonus.html. It does show in other browsers, other people can see it, but I cannot. Same with these websites: http://www.jokevan.nl/html5/oef3-3.html http://kokenvoorpapegaaien.nl/kellerhuis/oef3-3.html

Thank you for your instructions. I'v tried all of this but unfortunately it didn't solve the problem. Still no control panels.

In the meantime I found it: I've been really stupid. the javascript function happened to be off. All is working fine now. Sorry!
