Taking Data from Main Form

[Stemdriller]

I have the following dilemma

3 Forms

MasterForm

With A Sub Form called 'MasterSubForm'
'MasterSubForm' has a sub form 'MasterSubSubForm'

MasterForm
MasterSubForm
MasterSubSubForm

I need to get a value in the MasterSubSubForm from a Value in the MasterForm

Have tried =[Forms]![frmMasterForm]![SalesOrder] but just get Name?

Thanks
Gareth

Gareth,

Like this:
=[Parent].[Parent]![SalesOrder]
