Append NEXT and PREVIOUS to RADIO BUTTON
Question
I have been stuck with a code for a few days, and what I'm really trying to do is to append NEXT and PREVIOUS (link/button) on a radio button.
<div id="slides">
<ul class="options-list">
<li>
<input type="radio" class="getradiotomove" id="bundle-73" name="bundle_option" value="73">
<input type="radio" class="getradiotomove" id="bundle-72" name="bundle_option" value="72">
<input type="radio" class="getradiotomove" id="bundle-74" name="bundle_option" value="74">
</ul>
</div>
<div id="buttons">
<a href="#" id="prev">prev</a>
<a href="#" id="next">next</a>
<div class="clear"></div>
</div>
what I am trying to do here is that, when i click on next, it will select the radio button below it, so the code above has bundle-73, bundle-72 and bundle-74, says if the default selected is bundle-73, when i click next, it should select bundle-72.

Your HTML looks broken so I'm going to assume you really mean this:
<div id="slides">
<ul class="options-list">
<li><input type="radio" class="getradiotomove" id="bundle-73" name="bundle_option" value="73"></li>
<li><input type="radio" class="getradiotomove" id="bundle-72" name="bundle_option" value="72"></li>
<li><input type="radio" class="getradiotomove" id="bundle-74" name="bundle_option" value="74"></li>
</ul>
</div>
Then your next action would look like this:
$('#next').click(function() {
var $all = $('.getradiotomove'); // Get them all
var $current = $('.getradiotomove:checked'); // Get the current one
var index = $all.index($current) + 1; // Find the index of the next one
if(index >= $all.length) // Wrap around at the end
index = 0;
$($all[index]).attr('checked', 'checked'); // Check it.
});

This assumes that you only have the one group of radio buttons.
You should be able to sort out the previous action yourself.

Maybe somethining like this?
<ul class="options-list">
<li>
<input type="radio" name="bundle_option" value="73">
</li>
<li>
<input type="radio" name="bundle_option" value="72">
</li>
<li>
<input type="radio" name="bundle_option" value="74">
</li>
</ul>
and javascript:
$('#next').click(function(){
$('[name=bundle_option]:checked').parent().next().children('[name=bundle_option]').attr('checked', true);
return false;
});
