Code not working, cant change mun's textures/heightmap

[MrHappyFace]

This code is based off of some code from NovaSilisko's mod, Alternis Kerbol, but I cant figure out whats wrong

		
		public CelestialBody Mun;
		public CelestialBody Kerbin;
		public Texture2D MunColor;
		public Texture2D MunHeight;
		public Texture2D MunBump;

		private string path = "HappyFaceIndustries/Crap/Textures/";

                public void ChangeHeightMap(Texture2D map, CelestialBody cb, float deformity, double heightMapDeformity, double heightMapOffset)
		{
			GameObject OldHeight = cb.pqsController.transform.FindChild("_Height").gameObject;
			if (OldHeight != null)
			{
				//sets deformity
				foreach (PQSMod_VertexHeightNoiseVertHeightCurve2 c in OldHeight.GetComponentsInChildren<PQSMod_VertexHeightNoiseVertHeightCurve2>())
				{
					c.deformity = deformity;
				}
				//creates VertexMap
				PQSMod_VertexHeightMap VertexMap = OldHeight.GetComponent<PQSMod_VertexHeightMap>();
				//edits VertexMap, sets height map
				if (VertexMap != null && map != null)
				{
					VertexMap.heightMap.CreateMap(MapSO.MapDepth.Greyscale, map);
					VertexMap.heightMapDeformity = heightMapDeformity;
					VertexMap.heightMapOffset = heightMapOffset;
				}
				if(map = null)
				{Debug.Log("Crap: map null...");}
			}
		}

		public void ChangeColorMap(Texture2D color, /*Texture2D bumpMap,*/ CelestialBody cb, float blend)
		{
			//sets color map
			PQSMod_VertexColorMapBlend OldColor = cb.transform.GetComponentInChildren<PQSMod_VertexColorMapBlend>();
			if (OldColor != null)
			{
				OldColor.vertexColorMap.CreateMap(MapSO.MapDepth.RGB, color);
				OldColor.blend = blend;
			}
			//sets color noise
			PQSMod_VertexSimplexNoiseColor oldColorNoise = cb.transform.GetComponentInChildren<PQSMod_VertexSimplexNoiseColor>();
			if (oldColorNoise != null)
			{
				oldColorNoise.order = OldColor.order + 1;
				oldColorNoise.blend = 0.1f;
			}
			//sets scaledspace maps
			foreach (Transform t in ScaledSpace.Instance.scaledSpaceTransforms)
			{
				t.gameObject.renderer.material.SetTexture("_MainTex", color);
			}
		}
		public void Awake()
		{
			MunColor = GameDatabase.Instance.GetTexture(path + "MunColor", false);
			MunHeight = GameDatabase.Instance.GetTexture(path + "MunHeight", false);
		}

		public void Start()
		{
			foreach(CelestialBody CB in FlightGlobals.Bodies)
			{
				if(CB.name == "Mun")
					Mun = CB;
			}
			//Mun
			Mun.orbitDriver.orbitColor = XKCDColors.ReddishBrown;
			ChangeHeightMap(MunHeight, Mun, 700f, 1400d, -2000d);
			ChangeColorMap(MunColor, Mun, 1f);
		}

When i run KSP, it gives me this error:

NullReferenceException: Object reference not set to an instance of an object

at Crap.BaseCrap.ChangeColorMap (UnityEngine.Texture2D color, .CelestialBody cb, Single blend) [0x00000] in <filename unknown>:0

Well, you're not checking either MunColor or MunHeight for null before you use them in Start(). I'd start there.

Thanks for the quick reply, ill try that. another related question: what is the error message mean?

EDIT: i added this:

Debug.Log("Crap: Changing mun...");
			Mun.orbitDriver.orbitColor = XKCDColors.ReddishBrown;
			if(MunHeight != null)
			{
				ChangeHeightMap(MunHeight, Mun, 700f, 1400d, -2000d);
			}
			else
				Debug.Log("AndrewCrap: MunHeight = null...");
			if(MunColor != null)
			{
				ChangeColorMap(MunColor, Mun, 1.0f);
			}
			else
				Debug.Log("Crap: MunColor = null...");

And it still sadi the same debug message, but didnt say that MunColor or MunHeight were null either
