Vbulletin plugins

[echo@]

I hope someone could point me in the right direction here, im fairly new to vb so bear with me.

Im trying to to pass a php value from a varible to my navigation menu.

Im using a method from alistapart.com, that uses php to rewrite the current class in css.

What i have to do create a varible, in my case its

PHP Code:

$thisPage="Community"; 


after this i include the navagtion.php menu.

Ok so i know this menu works for the rest of my site but i cant get it to pass the varible.

I have created several plugins,

1. One to include the header (of my main script)
2. One to Set the $thisPage
3. One to include the navagation.php

I have enabled the plugin system and nearly everything works, only problem is that vbulletin justs prints the varible's value instead of storing it .

im calling the plugin $thisPage in my vb header file, and my plugin contains

PHP Code:

$thisPage="Community"; 


vb just prints the word "Community" ?

Any ideas
