This is what i'm doing..open a new level in wed..add a large hollow cube..and add a small cube in that hollow cube..add one light above the small cube and add a position(camera) somewhere in hollow cube..save it as "test" at new folder at desktop.then go to map properties and add a new script.this is what i write in the script :-

#include <acknex.h>
#include <default.c>

////////////////////////////////////////////////////////////////////////////////////

function main()
{
video_mode = 7;
level_load ("test.wmb");
}

then i build a map..when i run it came error..this script i copied from workshop08 and just change wmb files name..so, can someone please tell me why this happen or i make a teribble mistake in that step.cannot find the problem even i've read all the workshop and some AUM siries..
