How to refer to fields in subforms from Main form

[JrMontgom]

I have tried, using Allen Browne's help to refer to a field in a subform from a main form.
The Main form is named frmCEFList and the subform is named frmCEFNames and the field is [SubFundName]. This should be simple but it eludes me so I am obviously missing something. Any help would be appreciated.

Referring to a fieldname should pull value from the current record of subform. Is that what you want?

I always give subform container control a name different from the object it holds, like: ctrDetails.

In textbox on main form, try:

=[ctrDetails]![SubFundName]

or

=[ctrDetails].Form.SubFundName
