Hi!

when i run the demo 3.3.010 i got this.

msOpenSHPFile(): Unable to access file. (county) 

in the map file i have some paths or files , so i need
to know where are the next:

SHAPEPATH "data"   where are "data"?
LABELOVERLAP FALSE   What that's mean?
IMAGE graphics/reference_base.gif  where are "gif"?

in the LAYER i don't understand:
LAYER
  NAME landsat
  TYPE RASTER
  STATUS ON
  DATA landsat.tif   where is landsat.tif??
  OFFSITE 0
END

....
 QUERYITEM usclass
  QUERY
    EXPRESSION "421"
    TEMPLATE lakes.html
    JOIN "data/lakejoin.dbf" islake "type"
  END
                 Where are the files.dbf??

i only have the next files for run the demo:

       source of initializing html file
