What is causing this error? This isn't for anything nuke related and I am having trouble getting an account registered at the OsCommerce site in order to ask for help there with this. I am hoping someone here may be able to answer this.

Call to undefined function: tep_not_null() in /home/xxxx/public_html/xxxxx/includes/classes/language.php on line 74

$this->catalog_languages = array();
$languages_query = tep_db_query("select languages_id, name, code, image, directory from " . TABLE_LANGUAGES . " order by sort_order");
while ($languages = tep_db_fetch_array($languages_query)) {
$this->catalog_languages[$languages['code']] = array('id' => $languages['languages_id'],
'name' => $languages['name'],
'image' => $languages['image'],
'directory' => $languages['directory']);
}

$this->browser_languages = '';
$this->language = '';

$this->set_language($lng); ((This is line 74))
}

function set_language($language) {
if ( (tep_not_null($language)) && (isset($this->catalog_languages[$language])) ) {
$this->language = $this->catalog_languages[$language];
} else {
$this->language = $this->catalog_languages[DEFAULT_LANGUAGE];
}
}
function get_browser_language() {
$this->browser_languages = explode(',', getenv('HTTP_ACCEPT_LANGUAGE'));

for ($i=0, $n=sizeof($this->browser_languages); $i<$n; $i++) {
reset($this->languages);
while (list($key, $value) = each($this->languages)) {
if (eregi('^(' . $value . ')(;q=[0-9]\\.[0-9])?$', $this->browser_languages[$i]) && isset($this->catalog_languages[$key])) {
$this->language = $this->catalog_languages[$key];
break 2;
}
}
}
}
}
?>

I don't know this application but I would guess that maybe the language is not being set? Unless someone knows it you're probably out of luck except at the author's site.
