Getting the value of a string in config.yml

Hi everyone, I was trying to do some stuff inside an if statement just when the value of "open" (in the config.yml) is "yes".
The code without the if statement should be alright, I have already tried to run it alone.
The problem is that when I run the code with the if statement, it doesn't work (no errors, just doesn't do anything.)

Code:

int conf = getConfig().getInt("open");

if (cmd.getName().equalsIgnoreCase("giveaway")) {
    if (conf == 1) {
                getServer().broadcastMessage(prefix + ChatColor.BLUE + p.getName() + ChatColor.GRAY + " has entered the giveaway! Type " +
                        ChatColor.BLUE + "/giveaway " + ChatColor.GRAY + "to enter!");
                       
                        players.add(p.getName());
                        saveConfig();

 

I'm sorry I explained this wrong, I meant that I tried with Strings (yes and no), Ints (1, 0) and booleans but still doesn't work.

 

The config.yml just contains "open: 0", the fact is that I don't know how to check if that's a "0" or a "1"

 

Ok, I might have figured it out. Basically, there's something in the code that sets the "open" and "prize" strings to respectively "yes" and "a NFA account", but I can't find what does that. Here's my code, if it can help:

Code:
