see the 'important notes' section on http://mapserver.gis.umn.edu/docs/reference/mapfile/projection/?searchterm=projection and do some reading in general about projections.
You would never have 2 epsg codes in one layer in your mapfile.
The projection object in your layer defines what projection your shapefile is in.
The projection object in your overall map object defines how you want your overall map (all the layers) projected.
I can't help much more than this - you have to know your data and understand what projections your shapefiles are in natively and then understand the final projection you want your map to appear in.

Hi,
I still get the error. Do I put both projections in the map obj. and layer? How would the coded the projection file and the 3 unprojection files? I am confussed about that?

you have a typo in what you just wrote - it should be epsG not epsQ - I hope you have epsG in your mapfile.
The error that you're getting indicates that Mapserver can't find the epsg file so it can't find the epsg code.
On windows in a typical ms4w installation, your epsg file should be in
c:\ms4w\proj\nad\

Hi,
I changed my units and my scale bar looks better. I still cant get my layers working. I put them on default and put
PROJECTION "init=epsq:4326"
END
in the map object and it didnt like that. I get an error like msProcessProjection(): Projection library error. no system list, errno: 2 . What else can I try?
Thanks,
Albert

If your other layers are not projected, you mean that they are in 'geographic'. You still need to set a projection object for them.
Try
PROJECTION
"init=epsg:4326"
END
This is geographic with the datum set as WGS84. This might not be the proper settings for your data - you could have another datum... anyway - set this projection object in your mapfile to see if you can get it working. What will happen is that Mapserver will project these layers on the fly to match the projection in your MAP object.

Hi,
I add a projection map file of richland county. The other layers that I have are unprojective files. The roads file is all the road in the county. Right now they are not catagorized. Thats the way the other layers are. I just want to get the projection file loaded which is and also my layers which are not.
Setting it to default didnt seem to work.
Thanks,
Albert

perhaps you could provide a bit more information to us. What is the native projection of the roads, boundary line, and etc... layers? If it isn't in the same projection as specified in your MAP object,
PROJECTION
"init=epsg:26914"
END
then you also need to specify the projection in the layer object.
you also might want to try to put STATUS DEFAULT for the roads, boundary etc and that way they will ALWAYS be ON. If status is set to ON you have to make sure that your URL specifies layers=layername in order for it to be on.
Hope this helps,
