Toon Shader Working With Multiple Spotlight Shadows (Pro)

Hello all,

I've been working on making this toon shader from scratch. I have manage to get it to look great! However, it can't get shadows from multiple spotlights(it does work with directional), D:

 Shader "NateAGeek/ToonPostProcesing" {
     Properties { 
         _MainTex ("Post Image", 2D) = "white" {}
         _OutlineColor ("Outline Color", Color) = (1.0, 1.0, 1.0, 1.0)
         _OutlineThickness ("Outline Thickness", Float) = 0.1
         _OutlineThreshold ("Outline Threshold", Float) = 0.1
     }
     SubShader {
         Pass{
         CGPROGRAM
             #pragma vertex vertexShaderMain
             #pragma fragment fragmentShaderMain
             #pragma target 3.0
             #include "UnityCG.cginc"
 
             uniform sampler2D _MainTex;
             uniform float4 _OutlineColor;
             uniform half _OutlineThickness;
             uniform float _OutlineThreshold;
             uniform sampler2D _CameraDepthNormalsTexture;
             
             
             struct vertexInput {
                 float4 vertex : POSITION;
                 float3 normal : NORMAL;
                 float4 texcoord : TEXCOORD0;
             };
             
             struct vertexOutput {
                 float4 position : SV_POSITION;
                 float4 tex : TEXCOORD0;
                 float4 scrPos : TEXCOORD1;
             };
 
             vertexOutput vertexShaderMain(vertexInput input) {
                 vertexOutput output;
                 
                 output.position = mul(UNITY_MATRIX_MVP, input.vertex);
                 output.tex = input.texcoord;
                 output.scrPos = ComputeScreenPos(output.position);
                 
                 return output;
             }
             
             float4 fragmentShaderMain(vertexOutput o) : COLOR{
                 float dx = 1.0/_ScreenParams.x;
                 float dy = 1.0/_ScreenParams.y;
                 
                  float depthValue;
                  float3 normalValue;
                  DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, o.scrPos.xy), depthValue, normalValue);
                  float4 center = log(depthValue) + float4(normalValue, 1);
                  DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, float2(o.scrPos.x, o.scrPos.y + dy + _OutlineThickness*dy)), depthValue, normalValue);
                  float4 top = log(depthValue) + float4(normalValue, 1);
                  DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, float2(o.scrPos.x, (o.scrPos.y - dy) - _OutlineThickness*dy)), depthValue, normalValue);
                  float4 bottom = log(depthValue) + float4(normalValue, 1);
                  DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, float2(o.scrPos.x + dx + _OutlineThickness*dx, o.scrPos.y)), depthValue, normalValue);
                  float4 right = log(depthValue) + float4(normalValue, 1);
                  DecodeDepthNormal(tex2D(_CameraDepthNormalsTexture, float2((o.scrPos.x - dx) - _OutlineThickness*dx, o.scrPos.y)), depthValue, normalValue);
                  float4 left = log(depthValue) + float4(normalValue, 1);
                  
                 if(distance(center, bottom) >= _OutlineThreshold || distance(center, top) >= _OutlineThreshold || distance(center, right) >= _OutlineThreshold || distance(center, left) >= _OutlineThreshold){
                     return _OutlineColor;
                 }
                 return tex2D( _MainTex, o.tex.xy);
             }
         
         ENDCG
         }
     } 
     FallBack "Diffuse"
 }
 

I think the issue is with my second pass... Any help or info will help!
