Maximum Threads in Particular Forum

[fotografik]

I found this code in vb.org and would like to know if it can be implemented in VB3.6 (the previous code was for VB3.0).

if ($bbuserinfo[usergroupid]==X AND $foruminfo[forumid]==Z) {
$checkpostfromthread=$DB_site->query_first("SELECT count(*) as count FROM thread WHERE postuserid=$bbuserinfo[userid] AND forumid=$foruminfo[forumid]");
if ($checkpostfromthread['count']>Y) {eval(print_standard_error('canpostx'));exit;}
}

Note : X = usergroup; Z = forum; Y = # of threads max

I want to be able to check the number of threads that a user has in that particular forum before allowing the user to create a new thread.

Would appreciate if an expert coder could advise - if it can or cannot be done. Thanks.
