XP bar rendering

I have written the following code to replace the Experience bar with a new XP/Magic bar for my mod however, all it renders is a black rectangle.

public class GuiXPMagicBar extends Gui 
{
private Minecraft mc = Minecraft.getMinecraft();

@SubscribeEvent
public void onRenderExperienceBar(RenderGameOverlayEvent event)
{
	if (event.type == ElementType.EXPERIENCE && !mc.thePlayer.isRidingHorse())
	{
		event.setCanceled(true);

		if (this.mc.playerController.gameIsSurvivalOrAdventure())
        {
			ScaledResolution scaledresolution = new ScaledResolution(this.mc, this.mc.displayWidth, this.mc.displayHeight);
	        int w = scaledresolution.getScaledWidth();
	        int h = scaledresolution.getScaledHeight();
            this.mc.getTextureManager().bindTexture(new ResourceLocation("immersion:textures/gui/magicbar.png"));
            int cap = this.mc.thePlayer.xpBarCap();

            if (cap > 0)
            {
                int expl = (int)(this.mc.thePlayer.experience * (float)(183));
                int x = w / 2 - 92;
                int y = h - 32 + 3;
                this.drawTexturedModalRect(x, y, 0, 0, 182, ;

                if (expl > 0)
                {
                    this.drawTexturedModalRect(x, y, 0, 9, expl, ;
                }
            }
        }
	}
}
}

Any help would be appreciated.
