Where you wrote:
"All of the information from the ContactTable is found within the
GroupTable",

This will make things more difficult.
If you set up your tables so that the Group table has only the Primary key
from the Contact table, this allows easy set up of main form and subform.
Also you mention vendor number.

If you post back with a more complete description of what you are trying to
do, we will be able to suggest a workable table setup.
Once the tables are set up correctly, it will be much easier to build the
forms and subforms.

While I use Access often, I'm not much of a programmer but can read most
of
it.

My question is I am trying to build a form which pulls information from
two
different places:

ContactTable
GroupTable

All of the information from the ContactTable is found within the
GroupTable.
My objective is to have the user open the form and see the contact
information in a subform triggered from a vendor number, but not be able
to
change that information while being able to create a new record from other
fields.

Also, if the vendor number has not been used before, or no contact
information is available unlock the subform so the user can enter address
information.

Wish I could explain this better.
