Мои плохие ... Кладбища были определены, я не предоставил все функции. Вот оно ...

Эта строка ...
L.marker([mkrLat, mkrLon], {icon: mkrIcon}).bindPopup(mkrText).addTo(**lyrName[i]**);
выдает следующую ошибку ...
TypeError: Cannot read property 'addLayer' of undefined
Если я изменю lyrName [ я] к кладбищам слой заполняется по желанию.
Снова TIA для любой помощи. jdadwilson
