[mapserver-users] Mapfile & Brain Damage

List,
Sorry if I'm asking the obvious, but I decided to stop spinning my
wheels and start asking for help.

In a nutshell, I can't get all layers to render when I select them.
Depending on where I place them in the mapfile (or if I place them in
the mapfile at all), there seems to be an impact on the remaining
layers.

I'm trying to set up data layers for Census 2000 data. I downloaded the
Census Regions, Divisions, ZCTAs, Tracts, Block groups and Blocks. (For
the record, many of these polygon layers are like parent/child polygons.
For instance, a polygon of Census tracts would be the border for several
block groups. If I were to zoom into a block group, its border would be
the same for many (child) blocks. Therefore, if they were placed on top
of each other, (and depending on the order in which they are defines),
one might obscure the detail of the other.

No problem there. I'd expect that. But, I can't seem to put all these
layers in one mapfile and select any individual ONE and be sure it will
work.

The mapfile follows. I've moved layers around and around with no
consistent results. Right now, they are in the following order:
LAYER # Census_Tracts_Northeast_USA
LAYER # Census_Block_Groups_Northeast_USA
LAYER # Connecticut Blocks
LAYER # Massachusetts Blocks
LAYER # New Hampshire Blocks
LAYER # New Jersey Blocks
LAYER # Rhode Island Blocks
LAYER # New York Blocks (Downstate Area Only)
LAYER # Major_Highways
LAYER # Census_ZCTAs_Northeast_USA
LAYER # Cities
LAYER # Census_Divisions
LAYER # Census_Regions

Any guidance appreciated.
Kieran
