random numbers not showing up on preview mode?

My random Number is not showing up on preview mode I followed everything and double checked everything seems good?

html:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Let’s Make Random Numbers</title> <link rel="stylesheet" href="styles.css"> </head> <body> <h1>Let’s Make Random Numbers</h1> <script src="scripts.js"></script> </body> </html>

JavaScript: function randomNumber(upper) { return Math.floor( Math.random() * upper ) + 1; } var counter = 0; while (counter < 10 ) { var = randNum = randomNumber(6); document.write(randomNumber + ' '); counter += 1; }

Congratulations on resolving your issue. :+1:

But for future questions, be sure to use "Markdown" formatting. There's a pop-up "cheatsheet" below, or you can watch this video on code formatting.

I have the same issue, can't get one single random number and I can't figure out where I did wrong! P.s: my script file is already linked to html ! function randomNumber(upper) { return Math.floor( Math.random() * upper ) + 1; } var counter= 0; while ( counter < 10){ var randNum = randomNumber(6); document.write(randNum + ''); counter+=1; }

In future, instead of asking a question in an "answer" to another question, always start a fresh question.

But this code seems OK, and should generate 10 random digits. If you're still having trouble, start a new question where you can make a snapshot of your workspace and post the link to it.

And BTW, it's not necessary to concatenate that empty string. The "write" function will work with a number argument.

thank you, this is helpful, will definitely start a new question with a screenshot link

Just to be clear, I was suggesting a snapshot not a "screenshot". Click on the colored link word in the last comment for instructions on how to make them.
