What am I doing wrong?

It keeps saying "The 'document.write()' command wasn't called. Why?

script.js 
var count = 0;
while (count < 0) {
  document.write("hello"); 
  count += 1;
}

Hi Roy, you are almost there.

You are required to print out the value of the count variable to the console which means to have to pass the variable count to the document.write method. You also want to print the message to the console 26-times. At the moment you are checking if the variable count is smaller than 0 which means your loop does not run at all.

Your code should look like this:

var count = 0;

while(count < 26){
    document.write(count);
  count+=1;
}
