Forums Scripts & Popups raws problem...

Would someone tell me why, when i join several channels at one time the 'Topic was set..' text is shown twice?
example:
08:29 • Topic was set by Same on Wed Feb 26 23:24:30 2003
08:30 • Topic was set by Same on Wed Feb 26 23:24:30 2003

those are my raws

raw 332:*:{
echo -l $2 $_t • 3Topic ' $+ $3- $+ '
halt
}
raw 333:*:{
set %topic. $+ $2 $3
halt
}
raw 329:*:{
echo $2 $_t • Topic was set by %topic. [ $+ [ $2 ] ] on $asctime($3)
halt
}
