I am using this code as a part of a game I’m making. But for the purposes of finding out what was causing this bug I took the section of code into a new html document.
I am trying to use this code:

<html>
<script type="text/javascript">
Difficulty = Normal
function ChangeGameMode()
{
  alert (Difficulty + ' game started ');
  }
</script>
<button type="button" class="StartButton" onclick="ChangeGameMode()">Start</button>
</html>

When I click the button, I don’t get an alert. Nothing happens.

But if I don’t use the Difficulty variable in the alert – ie:

alert ('Normal' + ' game started ');

Then when I use that for the alert instead, it does work.
I am at conplete loss as to what is causing this and I have been pulling my hair out because of it. Any help would be appreciated.

    You haven’t properly defined the Difficulty variable. You need to assign it a valid value. Normal is not a valid javascript value. You need to wrap it in quotes:

    <html>
<script type="text/javascript">
var Difficulty = 'Normal';
function ChangeGameMode() {
    alert (Difficulty + ' game started ');
}
</script>
<button type="button" class="StartButton" onclick="ChangeGameMode()">Start</button>
</html>
