Help with variable in vBulletin

[Elmer]

Hi guys,
My problem is that I made some changes in the file index.php and I have created some variables there but they doesn't work in the HEADER template. My question is, How can I make them to work in the HEADER template?

It appear that they just work in FORUMHOME template but is not what I want.

Any help would be really appreciated.

define em in phpinclude or before the global.php is required

the header is parsed in global.php so you have to define them before
