   I have an error X3000: invalid target or usage string
  Hi,I have an error X3000: invalid target or usage string atfloat2 outerTaps[NUM_OUTER_TAPS];Any idea why?float4 hlsl_gaussian (float2 tapZero : TEXCOORD0,float2 tap12 : TEXCOORD1,float2 tapMinus12 : TEXCOORD2,float2 tap34 : TEXCOORD3,float2 tapMinus34 : TEXCOORD4,float2 tap56 : TEXCOORD5,float2 tapMinus56 : TEXCOORD6 ) : COLOR{   float4 accum, Color[NUM_INNER_TAPS];   Color[0] = tex2D(nearestImageSampler, tapZero); // sample 0   Color[1] = tex2D(linearImageSampler, tap12); // samples 1, 2   Color[2] = tex2D(linearImageSampler, tapMinus12); // samples -1, -2   Color[3] = tex2D(linearImageSampler, tap34); // samples 3, 4   Color[4] = tex2D(linearImageSampler, tapMinus34); // samples -3, -4   Color[5] = tex2D(linearImageSampler, tap56); // samples 5, 6   Color[6] = tex2D(linearImageSampler, tapMinus56); // samples -5, -6   accum = Color[0] * gTexelWeight[0]; // Weighted sum of samples   accum += Color[1] * gTexelWeight[1];   accum += Color[2] * gTexelWeight[1];   accum += Color[3] * gTexelWeight[2];   accum += Color[4] * gTexelWeight[2];   accum += Color[5] * gTexelWeight[3];   accum += Color[6] * gTexelWeight[3];    Here->    float2 outerTaps[NUM_OUTER_TAPS];   outerTaps[0] = tapZero * gTexelOffset[0]; // coord for samp 7, 8   outerTaps[1] = tapZero * -gTexelOffset[0]; // coord for samp -7, -8   outerTaps[2] = tapZero * gTexelOffset[1]; // coord for samp 9, 10   outerTaps[3] = tapZero * -gTexelOffset[1]; // coord for samp -9, -10   outerTaps[4] = tapZero * gTexelOffset[2]; // coord for samp 11, 12   outerTaps[5] = tapZero * -gTexelOffset[2]; // coord for samp -11,-12   // Sample the outer taps   for (int i=0; i<NUM_OUTER_TAPS; i++) {   Color = tex2D (linearImageSampler, outerTaps);   }   accum += Color[0] * gTexelWeight[4]; // Accumulate outer taps   accum += Color[1] * gTexelWeight[4];   accum += Color[2] * gTexelWeight[5];   accum += Color[3] * gTexelWeight[5];   accum += Color[4] * gTexelWeight[6];   accum += Color[5] * gTexelWeight[6];return accum;}thanks in advance,Alex
