Javascript problem to submit a form in Safari or Firefox

Hello all,

I have a form on a website that fetches info from a database to populate the dropdown lists, but some dropdown lists are dependent from what was selected from previous dropdowns. To remedy to this, every time one of the important dropdown changes, we force a submit of the form, through _javascript_ event binding, which loads the correct info into the dependent dropdown.

This works fine in IE, but not in Firefox or Safari. Curently, we use a .php page that loads an HTML template. That template contains the _javascript_ for the operation. Here's a sample of the code :

function page_membersSearch_s_talent_cat_OnChange()
{
    var result;
    document.forms["membersSearch"].submit();
    return result;
}

//
// If element exist than bind function func to element on event.
// Example: check_and_bind('document.NewRecord1.Delete1','onclick',page_NewRecord1_Delete1_OnClick);
//
function check_and_bind(element,event,func) {
var htmlElement = eval(element);
if (htmlElement) {
    if (typeof(htmlElement)=="object" && !htmlElement.tagName && htmlElement.length > 0)
    {
      for (var i=0; i < htmlElement.length; i++)
        eval(element+"["+i+'].'+event+'='+func);
    }else eval(element+'.'+event+'='+func);
}
}

function bind_events() {
    if (document.forms["membersSearch"]) check_and_bind('document.forms["membersSearch"].s_talent_cat','onchange',page_membersSearch_s_talent_cat_OnChange);
    if (document.forms["membersSearch"]) check_and_bind('document.forms["membersSearch"].s_gender_id','onchange',page_membersSearch_s_gender_id_OnChange);
    forms_onload();
}

If you could either tell me what is wrong with the code, or give me an alternate solution, I would be extremely grateful.

Thanks in advance
