I don't know what portal you are using. I am using CMPS.
To get this additional navbar working on the CMPS frontpage I had to go into my includes/vba_cmps_include_bottom.php and do the following:
Find:
PHP Code:
global $vboptions, $vba_options, $vbphrase, $stylevar, $bbuserinfo, $show, $pmbox;
Replace with:
PHP Code:
global $vboptions, $vba_options, $vbphrase, $stylevar, $bbuserinfo, $show, $pmbox, $navbar2;
Or you could have just added $navbar2 in it somewhere.
