Subnav (second navigation) problem

[Qtix]

Hi

I've got an website  ;) made in php  :o i make my pages with an Content Management System. But in the second navigation bar i need serveral links to different pages, so i made a code that whenever its that Title go to that page if not then show the content made by the management system. but i get to see double links, one from my PHP code and the other to the page created by my management system. When i delete the "else" code everything is fine only now i cant see my links to the pages made by my content management system. Everything i tried resulted in an error. and i know that using "if" several times isnt the right way but i cant think of something else.


/**

if (!isset($aVars['g']['c']) ||
!is_numeric($aVars['g']['c']))
$sSecondNav = null;
else {
$aCategory = array(
'von',
$aVars['g']['c']
);

$aOrderedSecondNav = processItems($aCategory);

//proccess current order
$sSecondNav = null;

if (!empty($aOrderedSecondNav)) {
for ($i = 0; $i <= max(array_keys($aOrderedSecondNav)); $i++) {
if (!isset($aOrderedSecondNav[$i]))
continue;
else
$aItems = $aOrderedSecondNav[$i];

$j = 0;
foreach ($aItems as $oItem) {
//obtain the first content
if (!isset($aVars['g']['id']) && $j ==0)
$aVars['g']['id'] = $oItem->getID();
