NOFLAG1 problem

I'm trying to set FLAG1 to on, for my skycube entity, so I can disable it in my Minimap(space themed)... I can do this manually in WED and get it to work but I don't usually create a BSP boxes for my sky (on a count of them having to be scaled so big to avoid clipping) but I can't seem to accomplish this with just code... if I can get it to work in WED it stands to reason it will work in code? Any advice would be welcome

Cheers

set(entity,FLAG1);

is that what you mean?

Yes, I suppose I should have included some code… I should know better. This is exactly what I mean, this is my code.
Code:

---

//First I create a sky cube.
ENTITY* skycube =
{
  type = "cariad_cube+6.tga"; 
  flags2 = SKY | CUBE | VISIBLE; 
}

//Then I create a second view.
VIEW* camera1_map =
{ 		
  layer = 1;
  pos_x = 0;
  pos_y = 0;
  size_x = 320;
  size_y = 240;
  arc = 35;
  aspect = 1;
  ambient = 10;
  fog = 10;
  genius = NULL;
  flags = VISIBLE | NOFLAG1;
}

//And last I create a simple function
function turn_me_off()
{
	set(skycube,FLAG1);
}

As you can see the code is far from complex. Why will this command not work on sky entities? Or is there no rhyme or reason?
