multistream rendering problem

Direct3D 10

supagu

im trying to get multi stream rendering working in dx10, i'm just hacking around with the multistream sample ATM.

(what ive got in comments is what was there origonally)

/*
  const D3D10_INPUT_ELEMENT_DESC vertlayout_singleindex[] =
  {
    { "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
    { "NORMAL",   0, DXGI_FORMAT_R32G32B32_FLOAT, 1, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
    { "TEXCOORD",  0, DXGI_FORMAT_R32G32_FLOAT,  2, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
  };
	*/
	D3D10_INPUT_ELEMENT_DESC vertlayout_singleindex[] =
  {
    { "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
		{ "COLOR", 0,	 DXGI_FORMAT_R32G32B32A32_FLOAT, 1, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 }, 
		{ "TEXCOORD0",  0, DXGI_FORMAT_R32G32_FLOAT,  2, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
  };
  UINT iNumElements = sizeof(vertlayout_singleindex)/sizeof(D3D10_INPUT_ELEMENT_DESC);
  D3D10_PASS_DESC PassDesc;
  g_pRenderScene_SI->GetPassByIndex( 0 )->GetDesc( &PassDesc );
  V_RETURN( pd3dDevice->CreateInputLayout( vertlayout_singleindex, iNumElements, PassDesc.pIAInputSignature, PassDesc.IAInputSignatureSize, &g_pVertexLayout_SI ) );



and in the shader:

(was just Normal, which i changed to colour)
struct VS_INPUT_SI
{
  float4 Position  : POSITION;  // vertex position 
  //float3 Normal   : NORMAL;		// this normal comes in per-vertex
  float4 colour	 : COLOR;
  float2 TextureUV : TEXCOORD0; // vertex texture coords 
};


then CreateInputLayout either crashes or returns hr = invalid args (0x80070057) so fails.
am i doing something noticably wrong

solved, had to change

"TEXCOORD0", to "TEXCOORD",
