Can't access variables in the advertisment HTML

[Retal]

Dammit, I found the solution in an older plugin of mine; I already solved this before.

For future reference

PHP Code:

$array['rotate_banner'] = rand(1,4);
vB_Template::preRegister('ad_global_below_navbar', $array); 


at the hook global_bootstrap_complete

Change the template name according to the ad position.
