Hi  all ,

I had created the following  Form/SubForm structure :

MainForm
      SubForm A (SubForm of  MainForm)
         SubForm B (SubForm of SubForm A)
           SubForm C (SubForm of SubForm B)
             SubForm D  (SubForm of SubForm C)

On each form I have a text box.
When The MainForm is open I had managed  to access the text box on
SubForm A
With the following command:

Dim ctrlSubForm As Access.SubForm
Set ctrlSubForm = FrmSubSubjectASubForm
ctrlSubForm(SubSubjectA).Enabled = True
ctrlSubForm(SubSubjectA).SetFocus
B = ctrlSubForm(SubSubjectA).Text

But using the same method to access SubForm B,C, and D I got an error
message.

Please help me.
Thanks.
