you should using "name" not "id" on inputs can shared.

html:

question 1 yes<input name='chk1' value="yes" type='radio' />no<input name='chk1' value="no" type='radio' /><br /> question 2 yes<input name='chk2' value="yes" type='radio' />no<input name='chk2' value="no" type='radio' /><br /> question 3 yes<input name='chk3' value="yes" type='radio' />no<input name='chk3' value="no" type='radio' /><br /> other comments<textarea id='comment'></textarea><br /><input type=submit name=submit value='post' /> 

jquery:

$('input[name="chk1"]').change(function(){     checkquestion("question 1", this.value); }); $('input[name="chk2"]').change(function(){     checkquestion("question 2", this.value); }); $('input[name="chk3"]').change(function(){     checkquestion("question 3", this.value); });  function checkquestion(text, value) {     if ($('#comment').text().indexof(text)<0)         $('#comment').text($('#comment').text() + text + ":" + value + "\n");     else {         var oldvalue = 'yes';         if (value==='yes') oldvalue = 'no';         $('#comment').text($('#comment').text().replace(text + ":" + oldvalue, text + ":" + value));     } }
