not sure why my code isn't printing to page

var html=''; for (var i = 1; i <= 10; i += 1); { html += 'div' + i + '</div>';

} document.write(html);

Not sure what you mean by not printing on the page, but I was able to get 11 to show via document.write

  var html = '';
  for (var i = 1; i <= 10; i += 1); {
    html += '<div>' + i + '</div>';  // You forgot the < > for your opening <div>
  }
  document.write(html);

HOWEVER... I followed the same code as explained in the video and got a "Uncaught SyntaxError: Unexpected token +=

I then changed the ending condition in the for loop to i++, then it worked, as shown in the video.

var html = '';
for (var i = 0; i <= 10; i++) {
  html += '<div>' + i + '</div>';
}
document.write(html);

Gena here's your code. I've went ahead and highlighted the errors...

var html='';

for (var i = 1; i <= 10; i += 1); { //There is a semicolon after your condition statement -- it's not needed.
    html += 'div' + i + '</div>'; //Also make sure you add the angle brackets (< >) to your html tags or they're just viewed as strings
} 
document.write(html);

Javascript like any other programming language is unforgiving when it comes to typos and syntax errors. Here's your code again after cleaning it up and removing the errors.

var html='';

for (var i = 1; i <= 10; i += 1) {
    html += '<div>' + i + '</div>';
} 
document.write(html);
