Multiple Table Forms

Hello Everyone,
I've searched for posts regarding this issue and have only found old ones related to prior versions of MS Access.
I'm using Access 2007 and I would like to create one form for data entry into multiple tables. Is this possible?
I've attempted to add the fields from the various tables, however it will only work when the data source is set to one table and will not input information into more than one table.
When the data source is set to multiple tables, it won't allow any data entry at all.
Is my only option to make seperate entry forms for each table or is it possible to create one main form, that will input data into several different tables?
Thanks for your help!

Try next:
In Recordset Type properties put ;
Dynaset (Inconsistent Updates)
Look at attachment (word, zip).
