[AccessD] Query/Forms Update Data

accessd at databaseadvisors.com

Using Access 2002.  Our Forms (based on a query) in general allows for
data entry.  However when I add another specific table and its link to
the main source of the query (another table) the query/form prohibits
produces results but does not allow for data entry/update?  How do i
determine what is causing this?  i could remove the linked table from
the query and the resultant form now allows for updating/data entry once
again.  I have tried to "look" at all the characteristics of the problem
table but find nothing that tells me it would preclude the form's
abitlity to update records.
