Forums mIRC Help help with an event

I wanted tried making an event where it reads from a text file

ON 1:TEXT:!show *:#shamguy4:/play -cn C:\shamguy4\file.txt

but apparently it doens work cause its not showing and i want it to be a notice so that only the person who triggers it sees it

i also wanted that after he triggers that something else happens -at the end it says a msg as a notice -a message that i set
how do i make a notice in an event?
and how do i make to things happen when one event is triggered?
