Clipping mask issue.. simple one but I can't see it.

Question

I want to fill the pattern into the shield.
Tried everything on this, it's so simple that I can not even see it.
Maybe it's the double lines on outline view?
Please help. Multi million dollar idea going to waste.

Kanokane,
I tried to just give a detailed list of things to do, with no explanation.
Fundamentally, you use a single path (which may be a Compound Path) as the Clipping Path of the Clipping Mask, and you select both that and whatever you have beneath it that you wish to clip.
When you apply the Clipping Mask, everything covered by the Clipping Path remains visible, and everything else becomes invisible; and the Clipping Path also becomes invisible, losing its Stroke and/or Fill (Fill in this case).
So when your shield is a rather thin Compound Path formed by the outer and the inner path, only the parts between those become visible, instead of filling the space inside.
1) is meant to keep the visible black outline formed by the Compound Path on top of everything else, and to bring a copy of either the outer or the inner path down beneath it; this is to serve as the Clipping Path; Alt/OptionClicking is to select the whole path, not just an Anchor Point or a segment.
2) is meant to bring the pattern down beneath the Clipping Path.
3) is meant to preserve the visible black outline formed by the Compound Path (by locking it) and to select the Clipping Path and the pattern (when the Compound Path is locked, you can just ClickDrag over everything and avoid selecting it), then apply the Clipping Mask.
4) is meant to have everything as a Group (consisting of the Compound Path and the Clipping Mask).
Whether you use the inner or outer path as the Clipping Path matters little; in the former case only the space inside the black rim is visible, in the latter case, the outermost part of it is hidden be the rim.
