got focus for control in subform

Can anyone help with this one?


I'm trying to set focus on DPR_Number control when clicking on DPR/Budget Information tab on a form. Is this the correct code? It's not working.

NAMES

Form name is NewPO

Tab contrl name is Tabctl31

Form on the tab control is DPR

Control on the form is DPR_Number

CODE

Controls!tabctl31!.SetFocus

Forms!DPR!.SetFocus

Controls!DPR_Number!.SetFocus


Also, I want the focus to move to a control in another page of the tab control (the Project Information tab) when the last control on the DPR form (Budget Amount in the DPR/Budget Information tab) has lost focus. How do I write the code for this?


Thanks so much!
