>Craig,
>This is the first Stored Procedure i've used. I've created a Primary key index in my database called "nextid". In the default, I put Getkey("MyTableName"), then I cut and pasted the code from your site. I'm not really clear on what a lot of the lines of this code does, so I really don't know what to change. Could you summarize it for me?

Make the DEFAULT value of the field the same as for the PK in my example. If the user cancels, you'll never get the number. You can think of stored procedures as a big PROCEDURE file that is always available to the data.
