null null null .. etc.. on following code:

var sentence = ''; while(sentence != 'The end.'){ sentence = prompt("Write next sentence. Type: 'The end.' to finish story."); document.write('<p>' + sentence + '</p>'); }

Is there a workspace bug?

By itself, this code seems to work as expected.

To facilitate a complete analysis, make a snapshot of your workspace and post the link to it here.

The code still seems to work in the complete environment. I only see "null" displayed if I press the "cancel" button instead of entering a paragraph.

Is that your issue? If so, you might want to add this as the 2nd line of the loop:

  if (sentence == null) break;

Otherwise, please describe what is happening more explicitly along what what you expect it to do differently.

Issue is not that you mentioned above and reproducible in Opera only. Chrome works as expected.

Console.log: 583port-80-6lb5bqawr4.treehouse-app.com/:1 A window.prompt() dialog generated by this page was suppressed because this page is not the active tab of the front window.

That error message is sure odd. Why would the page not be the active tab? Maybe it would help to add a "start" button to the page and use that to trigger the rest of the script (giving it that "user interaction").

I many not be help to help further on this one, I don't use Opera or have it installed.
