Auto-fill gone in input page?

It is so easy to change the audio attribute. In this HTML code:

<input type="radio" class="p5_blue_radio" name="includes_audio" id="includes_audio5" value="yes" checked="checked">

The text checked="checked" needs to move to this line:

<input type="radio" class="p5_blue_radio" name="includes_audio" id="includes_audio6" value="no">

Right? Just move the two words to another line?!
