help! function not defined error

verynoob · 11-22-2011, 03:53 AM

I know you guys can catch my error here. I'm very, very new to JavaScript and don't have the ability to catch simple syntax errors, which I think might be my problem here. I also get a "missing } after function body" error on line 1, which I don't think I actually have.

Code:

<!doctype html>
<html>
 <head>
   <title>Sum of Numbers Below N that are Multiples of 3 or 5</title>
	<script type="text/javascript">
   function sumOfMultiples(){
   //runs the sum of all natural multiples of 3 and 5 below 1000
   var i = 1, ans = '', sum = 0;

	//generate natural numbers 1 .. 999
	while(i < 1000){
   		//test: multiple of 3 or 5?
	    if((i % 3 == 0) || (i % 5 == 0)){
      	sum += i;
      	ans = ans + i + ' ';
   }
   ++i;
}
//display result
alert(sum);

 </script>
 </head>

 <body>
   <p>
     Contents of the page.
   </p>
   <input type="button" value="Sum of Mults" onclick="sumOfMulitples();">
   <hr>
   <div id="outputDiv">
     Welcome to my site!
   </div>
 </body>
</html>

sumOfMulitples is not the same as sumOfMultiples (mind the order of the letters)

And if you count the number of { and the number of } you'll see that you have 3 times { and only 2 times } ... that's a mismatch
