I've this a part of code during my functions.php:

function cc_admin_enqueue_scripts($hook) {
    $file_dir=get_bloginfo('template_directory');
    wp_enqueue_script('media-upload');
    wp_enqueue_script('thickbox');
    wp_enqueue_script( 'farbtastic' );
    wp_register_script('my-upload', $file_dir."/functions/scripts/rm_script.js",array('jquery','media-upload','thickbox','farbtastic'));
    wp_enqueue_script('my-upload');
    wp_enqueue_script('tablednd', $file_dir.'/functions/scripts/jquery.tablednd.js', array('jquery'), '0.5');
    wp_enqueue_script( 'jquery-ui-tabs' );
    wp_enqueue_script( 'jquery-ui-sortable' ); 
    wp_enqueue_script( 'jquery-ui-droppable' );
    wp_enqueue_script( 'jquery-ui-draggable' );
}
add_action('admin_enqueue_scripts', 'cc_admin_enqueue_scripts');

Everything works fine. The rm_script javascript works ok, except I acquired this error notification in IE:

Object does not support this property or method rm_script.js line 290

within the rm_script.js line 290:

(this is when line 290 begins:)

jQuery(".table_sort").tableDnD({
    onDragClass: "myDragClass",
    onDrop: function(table, row) {
    var $multitable_wrap = jQuery('.table_sort .multitable');
    $multitable_wrap.each(function(i) {
    var $current_sub_table = jQuery(this);
    $current_sub_table.find('.correct_num').each(function(){
    var $newname = jQuery(this).attr('name').replace(/\d+/,i);
    jQuery(this).attr({'name': $newname,'id': $newname});
        });});},
    onDragStart: function(table, row) { }
});

the jQuery(".table_sort").tableDnD may be the source where I acquired a mistake. Basically remove it, it really works all right, however i require it to aid my javascript function. I have declared the jquery.tablednd.js, but in some way .tableDnD function could not be loaded.

When you get a mistake stating that jQuery does not support this property or method, this means the tableDnd code has not been loaded correctly.

The very first factor to check on would be that the URL for jquery.tablednd.js is correct within this file and really being loaded (this can be done by copying the relative URL and pasting it in to the address bar of IE--making certain that you simply permit any relative pathways).

I'd be amazed in the event that wasn't the issue. Should you still will have the issue, could it be just restricted to IE, or will it affect other browsers? If you are using Opera (with FireBug) or Chrome and check out the console you may have the ability to discover more precisely what is going on wrong.
