The LISTBOX Get column formula command returns the formula associated with the list box column designated by the object and * parameters. Formulas can only be used when the “Data Source” property of the list box is either Current Selection or Named Selection. If no formula is associated with the column, the command returns an empty string.
If you pass the optional * parameter, this indicates that the object parameter is an object name (a string). If you do not pass this parameter, this indicates that the object is a variable. In this case, you pass a variable reference instead of a string. This parameter must designate a column of the list box.
