You can use this script

Code:
on *:TEXT:*:?:{
if ($1 == hi) {
/msg $nick Hi
}
if ($1 == hello) {
/msg $nick Hello
}
}


This will make the script trigger if someone pm's you and word one is hi or hello like this: Hi how are you?

If you want the script to trigger if someone only pm's hi or hello to you use this script

Code:
on *:TEXT:*:?:{
if ($1 == hi) && (!$2-) {
/msg $nick Hi
}
if ($1 == hello) && (!$2-) {
/msg $nick Hello
}
}

if ($me != geek) { $life is $false }
else { $life is $true }
