Question TileMap.SetTile not working :(

So I made a script that gets the color of the pixel in the texture2D, and then it places the color at the tile by order, I used some debugging and it looks like it goes through every stage and just the SetTile isn't working, It has the color and the location of the tile. The script:

Code (CSharp):

1.  Color Pcolor = PNGMap.GetPixel(x, z);
2.         print(Pcolor.a);
3.         if(Pcolor.a == 0)
4.         {
5.             print("No Color");
6.             return;
7.         }
8.         else
9.         {
10.             print("The Last Step");
11.             TMap.SetColor(new Vector3Int(x, 0, z), Pcolor);
12.         }
13.     }

The TIleMap is in XZ Orientation if that matter in some way

 

I did that, but it didn't work either. After asking the color of each tile after coloring it I figured out all of the tiles are "White" (even tho I don't see any tiles).
