Firefox Radio Button Weirdness

Question

I have a form with a lot of groups of radios. Each radio has a unique id and has the same name as the others in its group. The page validates as XHTML transitional.

Tested in IE6 & 7, Opera, Safari, and Chrome it works exactly as you would think it would from either mouse or keyboard input.

In FireFox it goes crazy. A single click on any radio in a group sets the first radio in the group checked. A double click on a radio usually selects it. Anyone seen this before?

Sample group looks like this:

<input type="radio" name="upAndDown_1" id="upAndDown_11" value="Y"  /> Y <br />
<input type="radio" name="upAndDown_1" id="upAndDown_12" value="N"  checked="checked" /> N<br />
<input type="radio" name="upAndDown_1" id="upAndDown_13" value="NA"  /> NA

The phonmomenon can be tested here: http://www.nolaflash.com/stackoverflow/firefox_and_radios.html

Any advice appreciated.

Answer 1

Doh! My designer had a single tag wrapping each group of radios. Eliminating the label tag fixes FireFox's weirdness.
