script to prompt an e-mail notification

[doc00]

Hi all,

I am a novice user, but I'd like to create a script in which:

If a date is entered into a field, an e-mail is sent (or some sort of reminder window or notice) on that date telling you that you need to call whomever or take whatever action.

Gotta say scripts are not the most intuitive items- for me, anyway. I've gone through my book, this website, and lots of trial & error (obviously,mostly error). Can you Fab Forum Folks out there help me?

Many thanks in advance- doc00
