hi sir,

i am using this code but not setfocuse to same field :-

Description about this code:-

Sex field is one combo box in two options male-1;female-2
IND_APPL is one combo box here options are applicable-1;not applicable-0

CODE:-

Private Sub IND_APPL_LostFocus()
If Sex.Value = 1 And IND_APPL.Value = 0 Then
Form_PHMRC.SIB1.SetFocus
IND_Line.SetFocus
Else
If Sex.Value = 2 And IND_APPL.Value = 1 Then
IND_N20.SetFocus
Else
MsgBox ("CHECK WITH SEX")
IND_APPL.SetFocus
End If
End If
End Sub

Sex.value = 2 and IND_APPL.value = 0 (ELSE block)
