For the php condition in CMS you should be able to use

PHP Code:

if (in_array($this->content->getNodeId(), array(1,2,3))) 


for line 3 of Lynnes code, where 1,2,3 is a comma delimited list of the nodeids of the article/sections that you want to show your tab as highlighted on.

Now, if you have your custom tab highlighted, you don't want the Home Tab highlighted at the same time. To prevent Home Tab being selected, edit Template vbcms_navbar_link

<vb:if condition="$vboptions['selectednavtab'] == 'vbcms' AND !in_array($nodeid, array(1,2,3))">

Add the red code to the condition in the first line of the template and replace 1,2,3 with a comma delimited list of the nodeids that you don't want to show the Home-Tab selected.
