Problem compiling shader code

Hi guys, I have a problem compiling this shader code. To be fair with you, I'm no specialist in shaders and probably the issue is quite small and somehow I can't see it. The compilation is performed for Android, thus with /Profile:OpenGL switch enabled.

VertexToPixel TexturedWithLightsVS(float4 inPos : SV_POSITION, float3 inNormal : NORMAL, float2 inTexCoords : TEXCOORD0)
{
VertexToPixel Output = (VertexToPixel)0;

Output.Position = mul(inPos, WorldViewProjection);
Output.TextureCoords = inTexCoords;

float3 Normal = normalize(mul(normalize(inNormal), xWorld));

Output.LightingFactor = dot(Normal, xLightDirection);
if (Output.LightingFactor<0.30f)
	Output.LightingFactor = 0.30f;
Output.clipDistances = dot(inPos, ClipPlane0);
Output.Position3D = mul(inPos, xWorld);
Output.Normal = (mul(inNormal, (float3x3)xWorld));
Output.View=dot(Normal,vecEye-Output.Position3D);
return Output;

}

PixelToFrame TexturedWithLightsPS(VertexToPixel PSIn) : SV_TARGET0
{
if (Clipping) clip(PSIn.clipDistances);
PixelToFrame Output = (PixelToFrame)0;

float diffuseLightingFactor = 0;// PSIn.LightingFactor + DotProduct(xLightPos, PSIn.Position3D, PSIn.Normal);

float3 N = mul(PSIn.Normal, PSIn.Position);

float D = saturate(dot(N, diffuseLightingFactor));

float3 R = normalize(reflectionPower * D * N - diffuseLightingFactor);


float S = pow(saturate(dot(R, PSIn.View)), 2)*specularPower;

float4 tmp = mul(PSIn.Position3D, xWorld);
float3 worldPosition = tmp / tmp.w;


float4 light0 = float4(0, 0, 0, 0);
if (Light0Intensity>0) {
	float3 L = normalize(Light0Position - worldPosition);
	float3 H = normalize(PSIn.View + L);
	float2 ret = lit(dot(N, L), dot(N, H), 1).yz;
	float intensity = max(L.x, L.z)*Light0Intensity;
	light0 = max(dot(L, PSIn.Normal), 0) * Light0Color *ret.y*intensity;
}


Output.Color = tex2D(TextureSampler, PSIn.TextureCoords) +light0;
Output.Color.rgb *= saturate(PSIn.LightingFactor) + 0.5f;

clip(Output.Color[3] < 0.1f ? -1 : 1);

float dist = distance(vecEye, PSIn.Position3D);
float fog = saturate((dist - FogNear) / (FogNear - FogFar));
Output.Color = lerp(FogColor, Output.Color, fog);

if (forceRed) {
	Output.Color.r = 1.0f;
}

Output.Color.a = transparency;
return Output;

}

technique TexturedWithLights
{
pass Pass0
{
AlphaBlendEnable = TRUE;
DestBlend = INVSRCALPHA;
SrcBlend = SRCALPHA;

	VertexShader = compile vs_3_0 TexturedWithLightsVS();
	PixelShader = compile ps_3_0 TexturedWithLightsPS(); 
}

}

And the error is:
error X5631: z or w components of vPos register are not available in this version, and cannot be dcl'd.

Could you please take a look at this?
