Hi. You declare the variable

var count = 0;

This needs to be output in the document.write.

   document.write(count )

Please also note that your variable is called count not counter. So the code should look something like this:

var count = 0;

while (count < 27) {
   document.write(count)
   count += 1;
}

Make sure you use the same name of your variable everywhere, and happy coding!
