hai all.......

i`m new in javascript...
i got crazy with this script because i was search in many tutorial and
learn online and do "try and error"
for 2 weeks to get variable value but still undefined :(

how i can get cookies all value without changing this script with
document.cookie?

<script language="javascript" type="text/javascript"><!--

function checkMemberForm24(frm){
if(!validateName(frm.elements['form[first_name]'].value)){
    alert('Please enter valid First Name!');
    frm.elements['form[first_name]'].focus();
    return false;
}
if(!validateName(frm.elements['form[last_name]'].value)){
    alert('Please enter valid Last Name!');
    frm.elements['form[last_name]'].focus();
    return false;
}
if((frm.elements['form[sex]'].value == 'Yes') && (frm.elements['form
[age]'].value == '')){
    alert('Age and sex Required!');
    frm.elements['form[age]'].focus();
    return false;
}

--></script>

<div id="divForm24"  class="formContent" id="frmMember24"
name="frmMember24">

(this)">
<div style="padding:5px;font-weight:bold;">Member Information</div>
<div class="formLine">
