An explanation for mickey pt :

The second form in my large application was a form to explain the settings that are seen on a form that has numerous ComboBoxes. So I have ComboBoxBph and ComboBoxDph, etc, etc, on one form and then you click a button Explain Settings and another form opens with explanations of the settings that you change with the ComboBoxes. So LabelBph on form ExplainSettings would explain setting Bph which is alterred using ComboBoxBph which is on the first form and not on the form that has the explanations.
