removeoaverlay(marker)

[pi5701]

ich komm hier nicht ganz weiter

möchte mit removeoverlay() meine marker entfernen da mit clearoverlays
auch die glayer wiki und pano resetted werden

da ich nicht viel ahnung von javascript hab is der code
zusammengewürfelt und ich weiss nicht wie ich nun alle marker
entfernen kann, mit removoverlay(marker)entfernt er immer nur den
zuletzt gesetzten marker

hier der hoffentlich relevante teil meines scripts

<script type="text/javascript">
