Enable/disable textbox depending on list option, list is dependent on Radio

Question

Hi,
I'm trying to enable/disable text_box which is dependent on select_list option, select_list is dependent on radio_button.
I'm able to enable/disable select_list using radio_button options, but I'm unable to handle text box which is again dependent on this SELECT_LIST item.
under html header page:-
<script type="text/javascript">
function disableOnValue(o)
if (o.value == 'Y')
document.getElementById('P86_Select_list_item').disabled = false;
else
document.getElementById('P86_Select_list_item').disabled = true;
document.getElementById('P86_text_box_item').disabled = true;
</script>
<script type="text/javascript">
$(document).ready(function()
$('#P86_Select_list_item').change(function()
if($(this).val() == 'Other')
$('#P86_text_box_item').attr("disabled", false);
else
$('#P86_text_box_item').attr("disabled", true);
</script>
under Region_Source of the region, whose Display point :- <b>Before Footer</b>
<script type="text/javascript">
if(document.getElementById('P86_radio_button_0').checked == true)
{disableOnValue(document.getElementById('P86_radio_button_0'));}
else
{disableOnValue(document.getElementById('P86_radio_button_1'));}
</script>
and under Radio_button item, HTML Form Element Attributes :- <b>onchange="javascript:disableOnValue(this);"</b>
also same way under text_box item , HTML Form Element Attributes :- <b>disabled</b>
any help

Thanks for replying Ben,
I have kept an example into apex workspace

application "Javascript" page 1
I'm able to enable/disable Select_list item & Text_box item with the help of Radio_button item(depending on user select yes or no option of the radio button)
But after selecting Yes option of the radio_button, only when user select "Other" option of the Select_List item the Text_box should be enabled otherwise it should be disabled for any of the options of the Select_list item.
I hope you understand my point.
