Walt,
You have posted your question to more than one forum. Please check my reply
in the "Forms Design" forum.
Tab controls do not have a row source. In other words, you cannot set a row
source or record set to a Tab Control.
Also, you do not have to create a sub-form for your data before you can use
a tab control. You can actually place controls on your tab control for
fields that are in the record source of the form on which you are placing the
tabl control.
A tab control is just another way of allowing users to view specific data in
an organized manner. The data that is displayed in a tab control can come
from many different sources.
