Prevent user adding record until current record is archived

[Moss100]

Hi there,

I have a two tables called Rooms & Guests

These are linked as one (Rooms) to many (Guests).


ROOMS TABLE GUESTS TABLE
Guests_ID
Rooms_ID >>> Room_ID_Link
Guest_Archived


I would like, as a safeguard some code to prevent the user from adding a new Guest record if there is currently a record associated with the room which is not archived.

I would greatly appreciate some help in forming code for this (my coding skills are very basic).

Many thanks Mark

The before insert event should help you.

Yes I was thinking of before insert - but how would I check if a record already existed?

Have a look at the DLookUp function
