[Mapserver-users] lat lon

Paul -

This is a bit of a shot in the dark, but in your PROJECTION block for the lat/lon data, take out the "unit=dd" statement.  It's not needed (and should be UNITS (plural) anyway) and might be breaking the projection.

You also don't seem to have a LAYER block surrounding the layer definition for your lat/lon data - but that should give you a map file parsing error.  Is your map file correct?
