That code was a pretty good description of your problem,
but the lines wrapped and had to be fixed before it would
compile and the error became clear to me.

To help avoid line-wrap in code, use the TWC
<http://www.physci.org/twc.jnlp>

Here is the fixed code, with comments. Note that this is an
SSCCE that spans only 68 characters width. Hopefully
it should not line-wrap.

<sscce>
import javax.swing.JOptionPane;

/* MonthlyBills.java - This program calculates the total
  of your monthly bills.
Input: Bill type and bill amount.
Output: Prints the total of your monthly bills. */
public class MonthlyBills
{
    public static void main(String args[])
    {
        /** Description of bill. */
        String billType;
        /** String version of bill amount. */
        String stringAmount;
        /** Amount of the bill. */
        double billAmount;
        /** Accumulates sum of bills. */
        double sum = 0;

        do
        {
            // This input statement asks the user to
            // enter a bill type or the word none.
            billType = JOptionPane.showInputDialog(
                "Enter bill type or the word done to quit.");

            // String comparison needs to be done using .equals()
            // to check equality of the contents, as opposed to
            // the String objects
            if(!billType.equals("done"))
            {
                // This input statement asks your user
                // to enter a bill amount.
                stringAmount = JOptionPane.showInputDialog(
                    "Enter amount of bill");

                // This statement converts the string version
                // of the amount to a double.
                billAmount = Double.parseDouble(stringAmount);

                //This totals up the amount of the bills
                sum += billAmount;
            }

        }while(!billType.equals("done"));

            // This statement displays the sum of monthly bills.
            System.out.println("Sum of monthly bills is $: " + sum);

            // This statement causes the program to exit.
            System.exit(0);

    } // End of main() method.

} // End of MonthlyBills class.
