Shader returning lots of ambiguous errors

I have the following code:

 Shader "VXR/Car" {
 Properties {
     _MainCol ("Colour", Color) = (1,1,1,1)
     _PaintTex ("Paint Texture", 2D) = "" {}
     _PaintCol ("Secondary Colour", Color) = (1,1,1,1)
     _AO ("Baked Ambient Occlusion", 2D) = "white" {}
     _Cube ("Cubemap", CUBE) = "" {}
     _RimPower ("Reflection Strength", Range(0.5,8.0)) = 3.0
     _SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1)
     _Shininess ("Shininess", Range (0.01, 1)) = 0.078125
     _BadgeTex ("Badge Texture", 2D) = "" {}
 }
 SubShader {
     Tags { "RenderType" = "Opaque" }
 
 CGPROGRAM
 #pragma surface surf BlinnPhong
 
 fixed4 _MainCol;
 sampler2D _PaintTex;
 fixed4 _PaintCol;
 sampler2D _AO;
 samplerCUBE _Cube;
 float _RimPower;
 half _Shininess;
 sampler2D _BadgeTex;
 
 struct Input {
     fixed4 uv_MainCol;
     float2 uv_PaintTex;
     fixed4 uv_PaintCol;
     float2 uv_AO;
     float3 worldRefl;
     float3 viewDir;
     float2 uv_BadgeTex;
 };
 
 void surf (Input IN, inout SurfaceOutput o) {
     o.Albedo = 1.0 - tex2D (_PaintTex, IN.uv_PaintTex).a;
     o.Albedo *= _MainCol;
     o.Albedo += _PaintCol * tex2D(_PaintTex, IN.uv_PaintTex).a;
     o.Albedo *= -tex2D (_BadgeTex, uv_BadgeTex).a;
     o.Albedo += tex2D (_BadgeTex, uv_BadgeTex).a * tex2D (_BadgeTex, uv_BadgeTex).rgb;
     o.Albedo *= tex2D (_AO, IN.uv_AO).rgb;
     half rim = 1.0 - saturate(dot (normalize(IN.viewDir), o.Normal));
     o.Emission = texCUBE (_Cube, IN.worldRefl) * pow (rim, _RimPower);
     o.Gloss = _SpecColor.a;
     o.Specular = _Shininess;
     o.Alpha = 1.0;
 }
 ENDCG
 }
 
 FallBack "Specular"
 }

It was all working until I added _BadgeTex, and then it returned 33 similar errors; Material doesn't have a --- property '---'

Any Help would be great, thanks in advance.
