Orders Database or file error

[jdimaging]

I have had to move my site from one server to another and since doing this I get this error:

 

Fatal error: Call to undefined function: display_links() in capricornleather.com/httpdocs/admin/orders.php on line 494

 

I went to orders.php and this is what it says:

 

<td class="smallText" valign="top"><?php echo $orders_split->display_count($orders_query_numrows, MAX_DISPLAY_SEARCH_RESULTS_ORDERS, $HTTP_GET_VARS['page'], TEXT_DISPLAY_NUMBER_OF_ORDERS); ?></td>
<td class="smallText" align="right"><?php echo $orders_split->display_links($orders_query_numrows, MAX_DISPLAY_SEARCH_RESULTS_ORDERS, MAX_DISPLAY_PAGE_LINKS, $HTTP_GET_VARS['page'], tep_get_all_get_params(array('page', 'oID', 'action')); ?></td>

 

I have no php or mysql experience and am at a total loss.

 

Your thoughts would be appreciated.
