That was a good catch by Nahum - MapLab/MapEdit requires the use of 
STYLE objects (as of MapServer 4.0 these came into effect) and if you 
don't use this object in your classes an error is thrown.  Actually we 
didn't even realize this problem until recently (the gmap-ms4w mapfile 
was recently modified with STYLE objects for this reason).  Sorry for 
this.  MapLab really should allow for both versions of mapfiles (with or 
without styles), since (as you saw with quickmap.php) mapserver does 
support both.
