Problem calling on JS function in page

Here’s my JS file that has been loaded into Header.php:

// NUMBER TO IMAGE CONVERSION
function counterimages(input) {
    var output = ""

    for (var i = 0; i < input.length; i++) {
        var chr = input.substring(i, i + 1)
        if (chr == '£') {
            output += '<img border="0" src="img/pound.gif">';
        } else if (chr == '.') {
            output += '<img border="0" src="img/dot.gif">';
        } else {
            output += '<img border="0" src="http://eatiply3.staging.wpengine.com/wp-content/uploads/2013/05/'+(chr+1)+'.png">';
        }
    return output;
}
// NUMBER COUNTER
var START_DATE = new Date("October 21, 2012 22:30:00"); // put in the starting date here
var INTERVAL = 1; // refresh interval in seconds
var INCREMENT = 769.2;  // increase per tick (1/0.0013 ~ 769)
var START_VALUE = 35000; // initial value when it's the start date
var count = 0;

jQuery(document).ready(function($) {
 var msInterval = INTERVAL * 1000;
 var now = new Date();
 count = parseInt((now - START_DATE)/msInterval) * INCREMENT + START_VALUE;
 $('#counter').html(count.toFixed(0));

 window.setInterval( function(){
    count += INCREMENT;
    $('#counter').html(count.toFixed(0));
 }, msInterval);

});

What it should do is show a number count-up at the given increment and interval, but substitute the numbers 0-9 for images named respectively.
I am able to make the second script work by plugging in <div id="counter"></div>Meals Provided into the WordPress page, but for the life of me I can’t get the numbers to convert to images. Here’s what I thought would work: `<script type=”text/javascript” src=”/js/counter.js”></script>
<script type=”text/javascript”>
<!–
counterimages(input);
//–></script>
<div id=”counter”></div>Meals Provided`

Thanks!
