jQuery

I am calling uploadify function ('#ControlName').Uploadify() by clicking on anchor element. But jquery(...).uploadify is not a function error is occuring. The code I have written is below

On .aspx Page

<input type="file" value="Upload Image" class="aReminderCreateUploadImage" id="aReminderCreateUploadImage">
</br>
<a class="aReminderCreateCancel">Cancel</a>

On .js File

$('.aReminderCreateCancel').live('click', function() {
    $("#aReminderCreateUploadImage").uploadify({
        'swf': 'Script/uploadify.swf',
        'uploader': 'Reminder.ashx',
        'auto': true,
        'multi': false,
        'buttonText': 'Add Photos',
        'onUploadSuccess': function(file, data, response) {
            $('.imgReminderCreate').attr('src', data);
        }
        , error: function(res) {
            alert("Outer Error :- " + res.d);
        }
    });
});

Both Scripts Uploadify.js and MyFile.js and CSS of Uploadify are referenced on aspx page.
