this is the working version of your code :

             {
 	              helpText.innerHTML = "Please enter a 9 digit Number";

you missed the function closing curly brackets. indent your code so you dont do such mistakes, also you can not give input name and span id the same thing, i changed it. the rest is your algorithm, which is not accurate yet, i didnt bother to correct it however.
