Alert generated from field

[dcecil]

I need to keep track of software licenses and hardware warrenties, but need to be alerted somehow when the current date reaches within 90 days of the expiration date field. Is this possible? If so, please describe in detail. I'm a fairly experienced user, but only moderately in the script area. I have managed, however to follow instructions to make pretty complicated scripts and calculations work.

Any help would be greatly appreciated.
