How do I change which radio button is selected using a function?

I have a radio group of 3 choices of which the first is selected by default. I want to make it to where the second one is selected upon clicking another item. This is what I have...

function selectSS()
{
    document.getElementById("width").value=16;
    document.getElementById("gauge_1").checked;
}

I then use onClick to call the function, the value of width changes to 16 like it is supposed to but how do I get it to select the radion button with the id gauge_1?

You have to set its checked state to true, so use:

document.getElementById("gauge_1").checked = true;

In your code, you're getting it and doing nothing with it.
