[mapserver-users] gmap75 Help

A further update!

I changed the first if block in gmap75.php3 to

if (isset($HTTP_POST_VARS))
  $HTTP_FORM_VARS = $HTTP_POST_VARS;
else if (isset($HTTP_GET_VARS))
  $HTTP_FORM_VARS = $HTTP_GET_VARS;
else
  $HTTP_FORM_VARS = array("");

to get by the problem of loading that, but ran into the following
problem that I have narrowed down to the line gmap75.php3:506

  $poLayer = $gpoMap->getlayerbyname($szLayerName);

which segvs when it it first called from gmap75.phtml:175 via
GMapGetStatus("road")

I don't think I can take this much further. 
Does anyone have a clue as to what I should check or do next?
