The markers are grouped as left justified (left edge of the envelope) or right justified (next to the indicia). The markers define the locations for the Graphic Ads.
To select a Graphic Ad, choose the marker, then select the Graphic Ad from the list (a checkmark appears in the checkbox).
NOTE: If the zone is empty, by default the right justified marker next to the indicia is automatically selected and the first Graphic Ad will appear in this location.
NOTE: To remove the Graphic Ad, simply select it again so that the checkmark is removed from the checkbox.
