Hi,
only CLASSes which have a NAME will show up in the legend. Try that first.
Best regards,

I am building a simple mapserver aplication....and i have problems with legend
.....i created a LEGEND object in the map file and in the index.php with
phpmapscript......the legend from mapscript produces a small PNG file where I
see a little square...when i comment the legend lines from mapscript i seen
nothing at all. Any suggestions(probably it is simple but i can't see it:)) )
here is my map file:
