Layer Membership Section
Contains one row that lists each layer to which the shape is assigned.
The layer assignment is shown as an index to the list of layers on the page. The layer index corresponds to the order of the layers in the Layer Properties dialog box (on the View menu, click Layer Properties). The first name in the dialog box is layer 0, the second is layer 1, and so forth.
If a shape is assigned to more than one layer, each layer index appears in the Layer Membership cell separated by a semicolon.
To refer to the value of the Layer Membership cell in a formula, use the name LayerMember.
