Shader problem?

I don't know where the mistake is?

I get this error:

 Giving up. Parser is hopelessly lost... 9
 Syntax error 25

Here is the code:

     Shader "Custom/vertexColorShader" {
     Properties
     {
         _Shininess ("Shininess", Range (0.03, 1)) = 0.78125
     }
     SubShader
     {
         Tags {"RenderType" = "Opaque"}
         CGPROGRAM
         #pragma surface surf BlinnPhong vertex:vert
        
         half _Shininess;
         struct Input
         {
             half2 uv_MainTex;
             fixed3 vertColors;
         };
        
         void vert (inout appdata_full v, out Input o)
         {
             o.vertColors = v.color.rgb;
             o.uv_MainTex = v.texcoord;
         }
        
         void surf (Input IN, inout SurfaceOuput o)
         {
             o.Albedo  = IN.vertColors.rgb;
             o.Specular = 1;
             o.Gloss = _Shininess;
         }
        
         ENDCG
     }
    
     Fallback "Specular"
 }

Code is from this youtube video (~ 05:10): Combining multiple materials into a single draw call
