so you want each enddate  to have its on table? If this is the case all you have to do is make a copy of the table structure. then build a append query to copy all data thats between 1st and the last day of that month.

I need to take one trade, for example ID #4446, and add duplicate lines with the date ranges for that trade by month. So that one trade would be expanded to 7 lines within the table.

4446          9/1/2010       9/30/2010
4446          10/1/2010      10/31/2010
4446          11/1/2010      11/30/2010
4446          12/1/2010      12/31/2010
4446          1/1/2011         1/31/2011
4446          2/1/2011         2/28/2011
4446          3/1/2011        3/31/2011

if you just want to view it in that format. you can just build a select query in that date range.

I really want something that will systematically copy the record and break the record into 7 identical records with different month ranges. If I can make a select query like this let me know how and I can easily append into the table.

You may have to export it to Excel to do the changes with the functions then import it back in.

Then this really needs to be a One to many design, with a "One" table (The Parent, Trades) and a "Many" table (the Child, TradeDates)

Here is a sample
I could have used a loop but I left it this way so that you could see the Date range formula progression throughout the months.

Examine it carefully, I am sure you will be able to adapt it to work in your database.
