Problem with HLSL shaders.

I'm working with D3D12, and I've run into another problem. I managed to fix my command list problem, but apparently something is going wrong with my shaders? My code currently is

struct Vertex {

DirectX::XMFLOAT3 position; // 3D position

DirectX::XMFLOAT4 color; // Color (RGBA)

};

// Define three vertices of a triangle

Vertex triangleVertices[] = {

{ { 0.0f, 0.5f, 0.0f }, { 1.0f, 0.0f, 0.0f, 1.0f } }, // Top (Red)

{ { 0.5f, -0.5f, 0.0f }, { 0.0f, 1.0f, 0.0f, 1.0f } }, // Right (Green)

{ { -0.5f, -0.5f, 0.0f }, { 0.0f, 0.0f, 1.0f, 1.0f } } // Left (Blue)

};

my shaders look like

// Define the shader type for switching between vertex and pixel shader
// Use the preprocessor macro to differentiate between shaders
#ifdef VERTEX_SHADER

// Vertex Shader Code
struct VSInput {
    float3 position : POSITION;
    float4 color : COLOR;
};

struct PSInput {
    float4 position : SV_POSITION;
    float4 color : COLOR;
};

PSInput main(VSInput input) {
    PSInput output;
    output.position = float4(input.position, 1.0f);
    output.color = input.color;
    return output;
}

#endif

#ifdef PIXEL_SHADER

struct PSInput {
    float4 position : SV_POSITION;
    float4 color : COLOR;
};

// Pixel Shader Code
float4 main(PSInput input) : SV_TARGET {
    return input.color; // Use the color from the PSInput structure
}

#endif
