Rails spinoffs - Mar 2006 - info about default value of InPlaceCollectionEditor

I have the follow code:
-------------------------------------
<script type="text/javascript">
function setupCategoryEditor(el, url, id_pagam) {

 var Element = document.getElementById(el);
 var editor= new Ajax.InPlaceCollectionEditor(el, url,
 {
  callback: function(form, value) { return
''op=pag_sca&value=''+value+''&id=''+id_pagam+''&id_cliente=8&id_order=22''
},
  onBlur: function(request) {Element.show(''indicator'')},
  collection: [[0,''No''],[1,''Yes'']],
  value: 0,
  ajaxOptions: {method: ''get''}
});
}
</script>
-------------------------------------
<div id="p_s_35" align="center">No</div>
<script type="text/javascript">
 setupCategoryEditor(''p_s_35'',
''save_pagam_sca.php'', 35);
</script>
-------------------------------------


I have a trouble about default value.
In the DIV p_s_35 I can see "Yes" or "No" and I
haven''t know how to  setup
a default value to 0 for "No" and to 1 for "Yes".

I have think a code like:
 value: function() {
    return ($(el).innerHTML==''Yes'') ? ''1'' :
''0'';
  },

but don''t run.

Can you help me?

Exchuse me for my very bad english :-P
