dynamically add objects in JavaScript


i have a form and when a user hits a certain radio button. I want a certain piece of html code to run. For example:

<input type='radio' value=0 name='myradio'>1
<input type='radio value =0 name='myradio'>2
now i want to add javascript to add a certain drop down menu depending on what radio button they selected, this is what i have so far:

<input type='radio' value=0 name='myradio' onclick = document.myform.myradio.value = 1>1
<input type='radio' value=0 name='myradio' onclick = document.myform.myradio.value=2>2

if(docuemnt.myform.myradio.value == 1) {
        write code
else {
        some other code
when i load this page, i get an errory saying that document.myform.myradio.value is either null or not an object.

My question is how can dynamically create html code, when a user select a radio button. Remind you that each radio button will produce different html code.

have a look at span or div tags and their innerHTML-attributes. It may (or may not) help.
