Ado0n help

hello to all I hope you can help. many users enter my chat and they put absent. I want them out if they stay 30 minits abcent

SOMTHING LIKE CODE OF OZZY BAT NOT WORK IN ME SCRIPT

raw 317:*: {
 if ($2 != $gettok($read(text\ozsleeper.txt, w,* $+ $2 $+ *),1,32)) && ($2 !isop $active) && ($3 >= %oz3sleep) {
   access $active add deny $2 1
   kick $active $2 : $+ Idle Kick-You've not moved for $duration($3) this is a chatroom not a bedroom wake up please(Access ban set for 1 minute)  
 }
}

You would have to probably whois the room to get a idle time or you use a timer to set the username to 0 everytime they do something in to the room. Like

set %idletime $+ morph3us 0 and a timer starts like 

/timer $+ $nick 0 1 inc %idletime $+ morph3us

Then u would have to put an if in to check the value of the variable. Im not sure if that would work but il try it when i get home. I hope this has helped in anoy sort of way.

Thanks
