/timer1 0 20 /ame is AWAY!
Timer1 will repeat an all channel action every 20 seconds until you stop the timer.
As the help file shows, just use it like that. Change the 0 to 1 if you want it send the message once and the 20 to 60 if you want it to wait 60 seconds instead of 20. That comes down to the following:
/timer 1 60 msg $nick hows things?
In your script, here's what it would look like. Note that I put things on separate lines to keep it clean. You can put things on one line if you really want that.
on *:TEXT:how are you:?:{
msg $nick Hey I'm good
.timer 1 60 msg $nick hows things?
}
You may also want to fix up the grammar there, but again, that's up to you.
Btw, you know that the matchtext you have there will not trigger if the person says "How are you?", right? The question mark would make it fail to match. You could put a wildcard on the end of that matchtext if you want it to trigger for any punctuation and other text that may follow.
