  • setChartBG Button

    Good morning guys!

    I am trying to place a button on a chart that will allow me to quickly change the chart background color but am having no luck. Thank you in advance.

    PHP Code:
    var fpArray = new Array();

    function 
    preMain() {
        
    setPriceStudy(true);
        
    setStudyTitle("Chart BG");
        
    setShowCursorLabel(false);
        
    setShowTitleParameters(false);
        
    setDefaultChartBG(Color.black);
        
        var 
    x=0;
        
        
    fpArray[x] = new FunctionParameter("aColor"FunctionParameter.COLOR);
        
    with(fpArray[x++]){    
            
    setName("Button Color");
            
    setDefault(Color.grey);
        }
        
    fpArray[x] = new FunctionParameter("bColor"FunctionParameter.COLOR);
        
    with(fpArray[x++]){    
            
    setName("Chart Color");
            
    setDefault(Color.black);
        }
        
    fpArray[x] = new FunctionParameter("cColor"FunctionParameter.COLOR);
        
    with(fpArray[x++]){    
            
    setName("Chart Color");
            
    setDefault(Color.white);                                                                             
        }
    }
    function 
    main(aColorbColorcColor) {
        
            
    drawTextPixel(012"@URL=EFS:ChartBG"nullaColorText.RELATIVETOLEFT Text.RELATIVETOBOTTOMnullnull"Button"4016);
        
        
        function 
    ChartBG(nButtonPressed) {
            if (
    getButtonPressed(nButtonPressed) == 1) {
                
    setChartBG(cColor);
            }
            else if (
    getButtonPressed(nButtonPressed) == 2) {
                
    setChartBG(bColor);
            }
        }
    }
    function

    nButtonPressed == BUTTON_LEFT) {
            return(
    1);
        }
        else if 
            (
