Getting Values from Subforms

[Ray]

I have the following:
Form1
Form1 has a Subform named Subform1
Subform1 has textbox named Text1

I added a new textbox to Form1 and set the record source to the following
= [Subform1].[Text1]

I get the following error message in the new textbox " #Name? "
I thought I did this before and it worked. Am I missing something?

=[Subform1].[Form]![Text1]
