i think this is what i used to have...

FUNCTION E, color, x, y, v, h

  FOR coord  0, N_ELEMENTS(h) DO BEGIN
    i = v[coord]
    j = h[coord]
    value[coord] = ABS(color[x+i,y+j] - color[x-i,y-j]) + ABS(color[x+2*i,y+2*j] - color[x,y])

  ENDFOR

  return, value

END



then i had a compile error and the problem was i forgot the = in coord = 0


so now it's like this

FUNCTION E, color, x, y, v, h

  FOR coord = 0, N_ELEMENTS(h) DO BEGIN
    i = v[coord]
    j = h[coord]
    value[coord] = ABS(color[x+i,y+j] - color[x-i,y-j]) + ABS(color[x+2*i,y+2*j] - color[x,y])

  ENDFOR

  return, value

END



but then it's saying that value is undefined...


but this was working before bb!!!!!!!!!!

this is sooooooo frustrating i don't get it
