                                      panelForRunner2.getRunner( ).getSeconds( ) +
                                      panelForRunner3.getRunner( ).getSeconds( ) ) / 3;

        DecimalFormat dfmt = new DecimalFormat( "###,###.##" );        
        primaryPanel.add( new JLabel( "Average time in seconds of all runners: " +

Now it's saying it can't find variable g.

r, g, and b are the RGB values for the colour. You'll need to set them to whatever colour you need

I understand that, I think it's referring to how i'm calling the custom color. Normally I would use Color.white. Right now I'm trying to use g.customColor. I'm assuming the g in customColor is what it's referring to. I've already modified the values for RGB. Thanks for your help!
