This is my code function randomNumber(upper) { return Math.floor( Math.random() * upper ) + 1; }

var count = 0; while(count<10){ var value = randomNumber(10); document.write(value + " "); count+=1; } It sometimes doesn't show the output and I'm not able to add space in between values!

There should always be a space between numbers because the code is adding one explicitly. :point_right: value + " "

Note that sometimes the number will be "10" (ten), but there should be a space between it and other numbers.

If you're not seeing consistent results, try restarting your browser or your whole machine. And perhaps try a different browser.
