How can i Fuse a 2nd Custom Ore into the World?

Trying to add a 2nd ore to Generate into the world, but when i tried the Tutorial, it keeps coming up with an Error


This is what I've got for a Single Ore - And it works

Code:

public void ModifyWorld()
{
    Main.statusText = "Adding Tin Ore..."; //feel free to tweak
    int Amount_Of_Spawns = 150+(int)(Main.maxTilesY/5); //feel free to tweak
    for(int i=0;i<Amount_Of_Spawns;i++) AddTinOre();
}
public void AddTinOre()
{
    int LowX = 200;                    //after ocean on left edge of map
    int HighX = Main.maxTilesX-200;    //before ocean on right edge of map
    int LowY = (int)Main.worldSurface;  //where the brown background and the sky background meets
    int HighY = Main.maxTilesY-200;    //where hell and the grey background meets
   
    int X = WorldGen.genRand.Next(LowX,HighX); //don't touch
    int Y = WorldGen.genRand.Next(LowY,HighY); //don't touch
 
    int OreMinimumSpread = 3; //feel free to tweak
    int OreMaximumSpread = 10; //feel free to tweak
 
    int OreMinimumFrequency = 3; //feel free to tweak
    int OreMaximumFrequency = 10; //feel free to tweak
 
    int OreSpread = WorldGen.genRand.Next(OreMinimumSpread,OreMaximumSpread+1); //don't touch
    int OreFrequency = WorldGen.genRand.Next(OreMinimumFrequency,OreMaximumFrequency+1); //don't touch
 
    WorldGen.OreRunner(X, Y, (double)OreSpread, OreFrequency, Config.tileDefs.ID["Tin Ore"]);
}

This is what i was trying to do:

Code:

public void ModifyWorld()
{
    Main.statusText = "Adding Tin Ore...";
    int Amount_Of_Spawns = 100+(int)(Main.maxTilesY/5);
    for(int i=0;i<Amount_Of_Spawns;i++) AddTinOre();
 
    Main.statusText = "Adding Coal..."; //feel free to tweak
    int Amount_Of_Spawns = 100+(int)(Main.maxTilesY/5);
    for(int i=0;i<Amount_Of_Spawns;i++) AddCoal();//notice how they both are different?? Good!!!
 
}
public void AddTinOre()
{
    int LowX = 200;                   
    int HighX = Main.maxTilesX-200;   
    int LowY = (int)Main.worldSurface; 
    int HighY = Main.maxTilesY-200;   
   
    int X = WorldGen.genRand.Next(LowX,HighX);
    int Y = WorldGen.genRand.Next(LowY,HighY);
 
    int OreMinimumSpread = 5;
    int OreMaximumSpread = 8;
 
    int OreMinimumFrequency = 5;
    int OreMaximumFrequency = 8;
 
    int OreSpread = WorldGen.genRand.Next(OreMinimumSpread,OreMaximumSpread+1);
    int OreFrequency = WorldGen.genRand.Next(OreMinimumFrequency,OreMaximumFrequency+1);
 
    WorldGen.OreRunner(X, Y, (double)OreSpread, OreFrequency, Config.tileDefs.ID["Tin Ore"]);
}
public void AddCoal() //This once is different than the other. Different name = no error!!! Good!!!
{
        int LowX = 200;                   
    int HighX = Main.maxTilesX-200;   
    int LowY = (int)Main.worldSurface; 
    int HighY = Main.maxTilesY-200;   
   
    int X = WorldGen.genRand.Next(LowX,HighX);
    int Y = WorldGen.genRand.Next(LowY,HighY);
 
    int OreMinimumSpread = 5;
    int OreMaximumSpread = 8;
 
    int OreMinimumFrequency = 5;
    int OreMaximumFrequency = 8;
 
    int OreSpread = WorldGen.genRand.Next(OreMinimumSpread,OreMaximumSpread+1);
    int OreFrequency = WorldGen.genRand.Next(OreMinimumFrequency,OreMaximumFrequency+1);
 
    WorldGen.OreRunner(X, Y, (double)OreSpread, OreFrequency, Config.tileDefs.ID["Coal"]);
}
 
}

And this was my Error

Where did i go Wrong?

there's only two mere errors.

the main one the compiler complains about is that you have one extra } in the end of your code , after you already closed everything..

the second , is that inside ModifyWorld you 'defined' Amount_Of_Spawns twice , remove 'int ' from the second time it appears , when you set it for the amount of coal ores.
