hey nate, try something like this

for (O=0;O<ArrayOfNumbers.length;O++)
{
if (ArrayOfNumbers[O] == 55)
     {
     //do whatever here;
     }
else {
     // do whatever if it isnt found
     }
}

hope it helps

Try this:

<script language=&quot;JavaScript&quot; type=&quot;text/JavaScript&quot;>
<!--

    var myArr = new Array (1, 2, 3, 55, 4, 5); // Array

    function findArrItem (arr, match) { // Array finding function
        for (i = 0; i < arr.length; i++) {
            if (arr[i] == match) {
                return true;
            }
        }
        return false;
    }

    if (findArrItem (myArr, 55)) {  // Statement to find array item
        alert (&quot;Item is found!!&quot;);
    } else {
        alert (&quot;Item isn't found!!&quot;);
    }

//-->
</script>
