Material doesn't have a color property '_Color'

I have been following a tutorial on how to code shaders and I have run into an odd problem which the Tutorial poster does not have, even though I checked for typos about 10 times and m eyes are starting to hurt. Could anyone look at my code and check if they can find what i did wrong ?

Shader "Shaders/2 - Lambert" { //Shader Path
	Properties { //Define any changeable properties here
		_Color ("color", Color) = (1.0,1.0,1.0,1.0) //Color property 
	SubShader { //Main Shader
		Pass {
			Tags { "LighMode" = "ForwardBase" }
			#pragma vertex vert
			#pragma fragment frag
			//User defined variables
			uniform float4 _Color;
			//Unity defined variables
			uniform float4 _LightColor0;
			//Base input structs
			struct vertexInput{
				float4 vertex : POSITION;
				float3 normal : NORMAL;
			struct vertexOutput{
				float4 pos : SV_POSITION;
				float4 col : COLOR;
			//vertex function
			vertexOutput vert(vertexInput v){
				vertexOutput o;
					float3 normalDirection = normalize( mul( float4( v.normal, 0.0 ), _World2Object ).xyz );
					float3 lightDirection;
					float atten = 1.0;
					lightDirection = normalize( );
					float3 diffuseReflection = atten * * max( 0.0, dot(normalDirection, lightDirection) );
					o.col = float4(diffuseReflection, 1.0);
					o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
				return o;
			//fragment function
			float4 frag(vertexOutput i) : COLOR
				return i.col;
	//loads Diffuse in case the Shader doesn't get loaded
	//Fallback "Diffuse"

Thanks in advance

Edit: exact error message: Material doesn’t have a color property ‘_Color’

Edit: for some reason getting another error message now: rc.right != m_GfxWindow->GetWidth() || rc.bottom != m_GfxWindow->GetHeight()

I think your “color” needs to be “_Color” on line 3? The _Color property name is used internally in the shader, whereas the bit in quotes is used for accessing that property via Material.GetColor(“_Color”) or Material.SetColor(“_Color”,someColor).

So I restarted my computer and both my error messages are gone but the lighting still doesn’t update here’s a link to the video I’m referencing off: 12:49

Tags { “LighMode” = “ForwardBase” }

Should be LightMode.

Actually material have not any colour property,but it has tendency to absorb or reflect the colour of light we can see the colour of the material which light is reflected by material.if a material is in white colour that means the all colour is reflecting by the material
