First off there are some semicolons you need to add. But the main problem is in your while loop, the condition is num = arr.length = is the assignment operator and == should be used for checking if two values are equal. Also, the while loop would never run because num == arr.length is never met. You should use another operator, and for what I think you are trying to do, you should use the < operator. The last problem is with the line: document.getElementById(ssc) It should be: var ssc = document.getElementById("ssc"); This is because the getElementById method returns an element so you have to assign it to a variable. Also, you needed quotes around the id parameter.
