I am printing variables in a custom window, but I can't get the commas to show up. If the variable is greater than 999, obviously, I would want the number to be comma separated.

#initialize the window
def self.initialize(x, y, w, h, opacity, back_opacity)
@window = Window_Base.new(x,y,w,h)
@window.contents = Bitmap.new(@window.width - 32, @window.height - 32)
@window.opacity = opacity
@window.back_opacity = back_opacity
end #method

#draw a single variable
def self.variable(x,y,w,h,i)
@window.contents.draw_text(x, y, w, h, "" + "" + "" + $game_variables[i].to_s, 0)
end #method

What do I need to do?

Thanks in advance for your help.

Adding the ' "" ' do nothing; it just adds an empty space character to the string. Try this:

Hmmm. I'm getting commas, but they are in the wrong space and the variable is printing with a different number than what it actually is.

It doesn't seem to be working.

Oh right, try this.
I was building the string backwards xD

It is coming up with a really strange value. I think it may be pulling all variables that have values other than 0 or something. It really isn't working...

It works for me.
Perhaps you're calling the wrong variable ID in the method call #self.variable(x,y,w,h, i )?
