A flash menu in PHP-nuke

i have a flash menu in my php-nuke site. One of the button’s URL is “my comments”. If you know some Mysql and php-nuke language, you may predict the URL as something like this:

on (release) {
//Goto Webpage Behavior
getURL(“modules.php?name=forums&op=my_comments&user=$user”,"_self");
//End Behavior
}

but this code cannot work, because the $user is selected from one table in the database. And no relation between flash button URL and database.

what can i do? with clickTAG, may i solve this problem, or no solution?

thank you in advance
