problem with line layers

[Sergio Lopez]

Hi all:
I have a problem with line layers. I use the following map file, and I
call it using http://localhost/cgi-bin/mapas/lp.map&mode=map, but the line
layers are not shown, just the background. But if I use this map file with
mapedit or gmap everithing´s ok. what am I doing wrong?
