[Mapserver-users] Layers added but not displayed !!!

[Dharani Babu]

Hi all ,
I am new bie who started working on mapserver with the help of the members 
of this group .
( credit goes to Tyler Mitchell , Paul spencer !!) .
I am trying to render TIGER files with OGR CONNECTION TYPE. I downloaded the 
tiger files  and have rendered the completechain of new hampshire - 
rockingham county . Its cool . I found the extent , layers details with 
ogrinfo .exe of GDAL . The output of ogrinfo <tiger folder> gaveme the 
following list of layers ::
Had to open data source read-only.
INFO: Open of `c:/ms4w/apache/htdocs/demof/data/rm'
using driver `TIGER' successful.
1: CompleteChain (Line String)
2: AltName (None)
3: FeatureIds (None)
4: ZipCodes (None)
5: Landmarks (Point)
6: AreaLandmarks (None)
7: KeyFeatures (None)
8: Polygon (None)
9: EntityNames (Point)
10: IDHistory (None)
11: PolyChainLink (None)
12: PIP (Point)
13: TLIDRange (None)
14: ZipPlus4 (None)
Now I can see the CompleteChain which displays the line work of the county . 
And I added the layers for Landmarks ( 5) , EntityNames (9) , PIP ( 12) also 
. Now I got a map with dots everywhere denoting landmarks and PIP . But I 
dont find any of the “Entity Names “ Why so ? And more over I expect the 
addition of Entity Names will display the Locations , city names , landmark 
names etc on the map . Am I right ? or missing something ? And what are the 
significance of other layers like AltName , FeatureIDs ,ZipCodes vis-vis 
rendering the map ?
When I tried to add the layers without geometry (TYPE  none ) what should be 
the TYPE value in LAYER definition ? And Can I add them as layers first of 
all ??Are they renderable or they are meant for some other purpose ??:)
My map file is as follows . Could any of you help  me ? Thanks in advance
