teacher points on California zips revisited

I made this change - no change in output. When I zoom into a zip polygon I
get the new legend reflecting my circle for teachers but I get not points
identified in the polygon.


#Joseph Norris (Perl - what else is there?/Linux/CGI/Mysql) print @c=map chr
$_+100,(6,17,15,16,-68,-3,10,11,16,4,1,14,-68,12,1,14,8,-68,4,-3,-1,7,1,14,-
68,-26,11,15,1,12,4,-68,-22,11,14,14,5,15,-90);

You need UNITS DD in your points layer where proj=latlong, or no UNITS
since DD is probably the default.
