I am trying to created a form in access which will contain two datasheets. The 1st datasheet will display data from a table with main account numbers. The 2nd datasheet will display data from a table with sub account numbers. I would like to be able to select a main account number in the 1st datasheet and have the 2nd datasheet display all sub accounts under that main account. I would also like to be able to enter/edit/delete from both datasheets. Any help would be appreciated. Thanks.
