James, Ok then are you saying that it is ok to put ALL the information that I have broken up on the 7 tables that I listed before (and the approx 5 that I did not spell out) into ONE table, since they are all information related to the "Client" : Who are they, who will pay, who is their doctor, who is their insurance carrier....

Naming and Relations Access 2K :VSMail mx3 40ffice (sorry, you didn't use your name), The easy answer to your question is that the limit to the number of columns in a single table is only limited by size. The best way to determine if you should break up your tables is to ask yourself if everything in the table refers to the Primary Key. In the case of your first table, that would be the client. One thing to remember about your look-ups, don't embed the data. Make a small table that houses the data and make sure that somewhere in your application you give a user (an Admin) the ability to add to that list if necessary. You are correct about the age being able to be calculated. There are some issues with calculating age though so be careful. You can make it display in any format you choose, although it may require that you do a little coding to get the exact format you wish. As far as your redundancy issues. You can leave certain fields inactive and unaccessible until the appropriate box is checked. You are venturing into territory where you will need the vba coding more and more though. I hope this helps. If you have any more specific questions feel free to ask.
