Hi Jeremy,

I would run ogrinfo on that table to see what field to use for your 
CLASSITEM, such as:

ogrinfo PG:"user=postgres password=postgres dbname=mdm6data 
host=mxsig-db port=5432" tutoiral.states_ugl_imported -summary

(your timing is good as the tutorial was recently updated for MapServer 8 )
