    Unhappy Unanswered: form / subform validation logic spiral

    Sort of an abstract question...

    What are some common ways of dealing with validations on a form and subform when the two are interdependent?

    For instance, in a parent/child set-up, in this case accounts/contacts...

    Form: 'accounts' (requires at least one associated contact for the 'account' record to be valid)

    Subform: 'contacts' (needs an existing 'actions' id in order to be created!)

    It's sort of a catch-22, and Access' automatic saving features are driving me a bit crazy. (i.e. when you move off the main form to the subform the record is saved automatically)

    Are these issues familiar to anyone?

    I'm guessing this is happening when you're adding a new record, so...

    In the parent form's AccountID field's AfterUpdate property, insert some code like this:

    If Me.NewRecord then
    Docmd.Runsql "Insert into tblContact (AccountID) values ('" & txtAccountID & "'")"
    end if
