would guess that this really is about the client-side map interface and not
about MapServer. Does your interface only allow them to click/select the
topmost layer? Do you pick which layer is selectable? Do you let
them pick which layer is selectable? Is it random?

understand what exactly you are trying to achieve here but it is not as
simple as map.getLayer(0) to get the topmost layer? And once you have the
layer object use one of the query function to select the record? E.g.
myLayerObj.queryByPoint ?</SPAN></P>
