Need scripting help

[darkweasel]

I'm currently trying to write a script that unbans every user banned
from the #pkmnwifi channel by the IRC server (i. e. flood kick) after
two minutes. However, I'm the biggest scripting n00b ever, so my idea
looked like this:

----------------
Event unbanwifi -after "*.*!*@* MODE #pkmnwifi +b *"
@ $unbanwifimasks[$unbanwificounter] = $4
timer unban$unbanwificounter 10 1 mode #pkmnwifi -b
$unbanwifimasks[$unbanwificounter]
$unbanwificounter++
timer rmcount$unbanwificounter 10 1 rmunbancounter
EndEvent

Event <OnStart_asdf> -after "*"
@ $unbanwificounter = 0
@ $unbanwifimasks = $null
EndEvent


Alias RMUNBANCOUNTER
$unbanwificounter--
EndAlias
----------------

Yeah, could somebody please help me doing that? (And sorry for
language mistakes, English is not my first language!)
