How do you use a hook for forumhome

[Moya]

I am trying to add in additional data into forumhome display by using product. I start out by test with this code

PHP Code:


global $test,$stamp;
$test='';
$stamp='';

                
$stamp=time();    
$test=12; 


The hook I use is forumhome_complete, and I add $stamp and $test to forumhome_forumbit_level2_post Template. When I refresh my forum with ctrl + f5, it returns empty value.

It seems to me that the plugin is not accessed. Would you please help me to place this into appropriate hook so that the routine can be carried out.

thanks a bunch
