Find & Replace Subforms

[Almost done]

I am trying just to put a simple find and replace command button on a
subform. BUT... The find and replace is only working for my master form, so
inturn not finding the records that I want. This is the event procedure...

Private Sub Command96_Click()
On Error GoTo Err_Command96_Click

Screen.PreviousControl.SetFocus
DoCmd.DoMenuItem acFormBar, acEditMenu, 10, , acMenuVer70

Exit_Command96_Click:
Exit Sub

Err_Command96_Click:
MsgBox Err.Description
Resume Exit_Command96_Click

End Sub
