Error on line with Custom sort order field Mod

[Tilapia Film]

I just installed the contribution "Custom sort order field for products in admin/categories.php"

 

But I am having some problems when the admin tries to execute the sort.

 

I get this error:

 

 

Fatal error: Call to undefined function: tep_set_product_sort_order() in /home/content/s/a/l/saltonseadoc/html/saltonseadoccom/shop/catalog/admin/categories.php on line 36

 

 

Here is the code in the area from 19 to 46:

 

 if (tep_not_null($action)) {
   switch ($action) {
//sort order

     case 'beginsort':

       $sorting = true;

       break;

       tep_redirect(tep_href_link(FILENAME_CATEGORIES, 'cPath=' . $HTTP_POST_VARS['cPath']));

     case 'setsortorder':

       for ($i=0, $n=sizeof($HTTP_POST_VARS['products_id']); $i<$n; $i++) {

           tep_set_product_sort_order($HTTP_POST_VARS['products_id'][$i], $HTTP_POST_VARS['sortorder'][$i]);

         }

       $sorting = false;

       tep_redirect(tep_href_link(FILENAME_CATEGORIES, 'cPath=' . $HTTP_POST_VARS['cPath']));

       break;

//end sort order

 

and here is the specific line 36 that it speaks of:

            tep_set_product_sort_order($HTTP_POST_VARS['products_id'][$i], $HTTP_POST_VARS['sortorder'][$i]);

 

Any help would be greatly appreciated!!!!

 

Thanks so much.

From what I can find, this seems like it could be a problem of it writing to the database. Does this seem like the issue?
