Parse Multi-line box

Hello again,

I would like to paste a static chunk of text into a multi-line box and, on Trigger, have it take a substring from the first line and place it in my customer name field, then take the second line and have it place the phone number, third line, etc.

I see information in the manual about the substring and I think I can manage this, however is it possible for me to choose a particular line from the multiline box to do something to?

Cheers!

Rick
