Access Query

["semi star gazer" <webforumsuser@xxxxxxxxxxxxxx>]

Hi, I am trying to write a delete query in Access, but not sure where to start.

 I have two tables, request and week1, that share a field, "id".

 I want to keep all of the records in request, but delete any records in week1 
that do not have an id that is also present in request.

 Please help! Thanks.
