Simple conditions can be used to create simple constraints. For example, you can use them to set up the condition for which the user, while configuring the lamp, cannot select a red shade if he or she has selected plastic for the material. If the user selects a red shade, value 'plastic' will no longer be available for material. Simple conditions consist of a field compared with a value. Simple conditions can consist of one or more lines. In that case, the lines are combined by a logical OR.
