Can anyone help me. I am having a major brain cramp. I have built a database that has 2 tables in it, a main_project&#039;s table and a sub_projects table. In the main table I have 3 fields, ID,DATE, and USERNAME. I have the DATE and USERNAME as Primary Keys. In my Sub table I have ID, USERNAME, LOCATION, HOURS, and COMMENT. I have ID and USERNAME primary keys. I have a relationship set up between these too but when I go to enter in a user twice I get an error saying that I can not have duplicate, when I change it to accept duplicates the database doesnt work. I am needing to have a database where a user can enter in multiple location, hours, comment for a single date. I dont know what I am missing.<BR><BR>Any help would be great.<BR>
