    Hello.

    I'm trying to make a function that will take a range and associate a rgb color with each increment in that range, applying a lighter shade or darker shade depending on how high or low the number in question is. However my code isn't working, and I was wondering if it was because of the way my function is set up. Can you reference a variable from a previous function in a new function, or do you have to call the function inside of the second function?

    Here's my problem:

    var a = [
    {X: 12},
    {X: 15},
    {X: 13},
    {X: 19},
    {X: 11},
    {X: 10}

    ];

    var max = 19; //this will be done with 2 underscore functions later

    var min = 10;

    function convert(){
    var i = (Math.round(255*a("X")/max));
    return i;
    }


    function drawThings(){
    for(var i=0; i< a.length; i++){
    var tag = $("<div>a</div>");
    tag.css("background" + "(" + "function convert();" + ", " + "function convert();" +" , "+ "function convert();" + ")");
    $("body").append(tag);
    }
    }

    drawThings();
