multiple answers, but I only want one
<p>I have created several if else statements, along with parsing a double and then the answer is the double = each of the else statements. When i run the program it runs beautifully, except  that each answer if given...</p>

<pre><code>//Makes a variable for the entered amount
            double mercurypf;
            double venuspf;

            double jupiterpf;
            double saturnpf;
            double uranuspf;
            double neptunepf;
            double plutopf;

    }

<p>The answer will be 0.0 0.0 0.0 9.1 0.0 0.0 etc.... remaining 0.0 for everything but the planet that was selected> i know this is due to MY =mercurypf + plutopf ... is there a way to steer clear of having to do that, yet still return a result for the radio button they choose?</p>
