    myFunction = function(){

    alert("Enter the first length of your room");
    alert("Enter the second length of your room");
    alert("Enter the third length of your room");

    alert("FAQ What happens if i want one wall one colour and another wall the other...... At the moment this app cant calculate that");
    };

    var height = prompt ("Please enter Your Height");
    var lengthArray = [];
    for ( i = 0 ; i<4; i ++ ){
    var length = prompt ("Please enter your lengths");
    lengthArray.push(length);
    console.log(lengthArray);
    var area = height * length;
    }
    // Paint Cost
    var Economy = 0.45;
    var Standard = 1.00;
    var Luxury = 1.45;
    var underCoat = 0.50;
    var paintCost;
    var undercoatCost;

    // The if stament for the standard costs
    var paintChoice = prompt (" Please Choose your paint ");
    if (paintChoice === "Standard"){
    paintCost = (Standard*area);
    console.log("The cost of this paint will be " + paintCost);
    }
    // The if stament for the standard costs
    else if (paintChoice === "Economy"){
    paintCost = (Economy*area);
    console.log("The cost of this paint will be " + paintCost);
    }
    // The if stament for the standard costs
    else if (paintChoice === "Luxury"){
    paintCost = (Luxury*area);
    console.log("The cost of this paint will be " + paintCost);
    }
    // This is the else if stament for the choice of selecting a wrong colour
    else if (paintChoice === "Red"){
    console.log("You have chosen the wrong paint choice ");
    }
    // This is the the if stament for undercoat when you choose yes
    var underCoat = prompt ("Would you like any undercoat? ");
    if (underCoat === "Yes"){
    undercostCost = (area*underCoat);
    console.log("The cost of the undercoat will be " + undercoatCost);
    }
    // This is the else if statement for undercoat when you choose no
    else if (underCoat === "No"){
    console.log("You have chosen not to have undercoat ");
    }
    // This is the variable to total up the lengths
    var total = [];
    var lengthSum = lengthArray[0] + lengthArray[1] + lengthArray[2] + lengthArray[3];
    console.log(lengthSum);
    var area = (height*lengthSum);
    alert("The area of the room is " + area.toFixed(2));
