[antiheld2000]

hi,

i got a silly little question:
ho do i pass a variable from a function to a callback? see this
example for better understanding:

var options = {
          success:       showResponse,
          url:                  'inc/application.adv.func.php'
 };

function showResponse(responseText, statusText)  {
        jQuery('div#adv_content').load('inc/de.application.adv.inc.php?
page='+pageNumber);
}

$('#step1').click(function(){
        var pageNumber = '0';
        $('#myform').ajaxSubmit(options);
        return false;
});


can you help me?
