Return method, Calculation Error
<p>I wrote the following program:</p>

<pre><code>    public double calcElectricityCO2(double avgBill,                                         double avgPrice)
    {
        return (avgBill/avgPrice)*1.37*12;

    } 
    public static void main(String[ ] args)  
    {
        double avgBill = 338.59;
        double avgPrice = 0.12;
        double emmision = calcElectricityCO2(avgBill,avgPrice);
        System.out.printf("Annual CO2 Emission from Electricity Usage: %1.2f %n",emmision);
    }     
}
</code></pre>

<p>When run it reports an error on <code>double emmision = calcElectricityCO2(avgBill,avgPrice);</code> What did I do wrong there?</p>
