Solved [} else if ] error

Hello,
first of all , I just joined forums because I always refer for help on here but I never really got a chance to make an account since I'd find any answer no problemo.
For the last like 3 hours, I have been trying coding a plugin that will change gamemodes, just to mess around with it, not anything special. But it seems that in Eclipse, it underlines the else on the code and I cant really use it. I tested without the else and the plugin is working just fine (I just removed those 3 lines).
Here is my code:

Code:

package me.witherstyle.spigot;

import java.util.logging.Logger;

import net.md_5.bungee.api.ChatColor;

import org.bukkit.GameMode;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {
public static Main plugin;
public final Logger logger = Logger.getLogger("Minecraft");

@Override
public void onEnable() {
    PluginDescriptionFile pdfFile = this.getDescription();
            this.logger.info( pdfFile.getName() + ("version" + pdfFile.getVersion() + ("is now enabled!")));
}

@Override
public void onDisable() {
    PluginDescriptionFile pdfFile = this.getDescription();
            this.logger.info( pdfFile.getName() + ("version" + pdfFile.getVersion() + ("is now disabled!")));
}
public boolean onCommand (CommandSender sender, Command cmd , String commandLabel, String[] args ) {
    readCommand((Player) sender, commandLabel);
    return false;
}

public void readCommand(Player player, String command ) {
    if(command.equalsIgnoreCase("gmc")); {
    player.setGameMode(GameMode.CREATIVE);
    player.sendMessage(ChatColor.DARK_GREEN + ("Gamemode changed to CREATIVE."));
    }
    else if(command.equalsIgnoreCase("gms")); // The error is here
    player.setGameMode(GameMode.SURVIVAL);
    player.sendMessage(ChatColor.DARK_GREEN + ("Gamemode changed to SURVIVAL."));
   
}
}

Thanks for trying to help me out. Any help will be appreciated!
Regards
