Fatal error undefined function

Hi,

I have some code in a custom module that checks if a node exists with a pmid using

$dup = biblio_pm_check_pmid($pmid);

and if not, it uses list($nids, $dups) = biblio_pm_import_ids(array($pmid)); So I was testing the code and encountered this problem:

Fatal error: Call to undefined function biblio_save_node() in C:\wamp\www\drupal7\sites\all\modules\biblio\modules\pubmed\biblio_pm.module on line 328
(...)
22 0.6029 32891176 biblio_pm_import_ids( ) ..\my_module.module:26
23 1.9867 32980176 _biblio_pm_create_node_from_xml( ) ..\biblio_pm.module:257

I fixed by adding:

function _biblio_pm_create_node_from_xml($xml, $terms, $batch, $session_id) {
  module_load_include('php', 'biblio_pm', 'EntrezPubmedArticle');
--> module_load_include('inc', 'biblio', 'includes/biblio.import.export');
  $nids = array();

Could you check it please?

Thanks
