ListView invalid property value???

[Richard Alvarez]

I think my code is correct but somehow I got this invalid property value.
What could possibly be wrong? i did a review on my access tables and naming conventions but still can't find anything.

 Private Sub lstMaster_DblClick()
    If Not (Me.lstMaster.SelectedItem Is Nothing) Then
        frmNew.txtID.Text = Me.lstMaster.SelectedItem.SubItems(0) <-- error was here
        frmNew.txtFName.Text = Me.lstMaster.SelectedItem.SubItems(1)
        frmNew.cboPosition.Text = Me.lstMaster.SelectedItem.SubItems(2)
        frmNew.txtStatus.Text = Me.lstMaster.SelectedItem.SubItems(3)
        frmNew.txtRate.Text = Me.lstMaster.SelectedItem.SubItems(4)
        frmNew.dtpStart.value = Me.lstMaster.SelectedItem.SubItems(5)
        frmNew.dtpEnd.value = Me.lstMaster.SelectedItem.SubItems(6)
        frmNew.txtAge.Text = Me.lstMaster.SelectedItem.SubItems(7)
        frmNew.txtAddress.Text = Me.lstMaster.SelectedItem.SubItems(8)
        
        frmNew.cmdUpdate.Caption = "&Update"
        
        frmNew.Show
        Unload Me
    End If
End Sub
