Why don't my buttons work?

I've checked the code and tried two browsers(firefox and chrome). I had this issue on another workspace preview.

If you make a snapshot of your workspace and post the link to it here, we could take a look.

It looks like you just have a typo, on line 45 there is "addEventLIstener" (capital "I") instead of "addEventListener" (lower-case "i").

I spotted a few more as well:

  • on line 48, "parenNode" instead of "parentNode"
  • on line 50, "extContent" instead of "textContent"
  • also on line 52, "extContent" instead of "textContent"

Perhaps the "t" keyboard button is becoming intermittent?
