plz help me to make a script that detects a word or phrase in a dcc window... or in chat window... like if you ctcp chat sumone...
and if that word/phrase was detected an input box will popup then it will ask an input then after the input it will clear the window... just clear... sorry i dont know scripting...

not sure what you mean totally,
but..

example:
on *:chat:*hello*:{
//msg =$nick message here
}
}
so if you wanted on dcc chat trigger hello
it came up with an input box:-
on *:chat:hello*:{
//msg =$nick $$?="Input Here"
}
}
that would
msg the open dcc chat what ever you want to input
to clear the window
just /clear
to close the window:
/close -c $nick
check out /help on chat

i mean after i input sumthing it will automaticaly clear the window...
how can i do that???

'/help on INPUT' and '/help /clear'

the help file is your friend
