javasvript not working

[buzzby]

<script language="JavaScript" type="text/javascript">
<!--
function x(){
return;
}
function validate(){
	if ((document.getstartedform.name.value=='') || (document.getstartedform.email.value=='') || (document.getstartedform.mobile.value=='')){
		alert('Please check all fields again before submitting as there are some missing entries');
		return false;
		}

 if ((document.getstartedform.doyouneed[0].checked == false ) && ( document.getstartedform.doyouneed[1].checked == false ) && ( document.getstartedform.doyouneed[2].checked == false ) && ( document.getstartedform.doyouneed[3].checked == false ))
    {
     alert ( "Please register your type of need" );
     return false;
    }
	else {
	return true;
	}
}
//-->
</script>

part of this code works and part does not.

this part works:

if ((document.getstartedform.name.value=='') || (document.getstartedform.email.value=='') || (document.getstartedform.mobile.value=='')){
		alert('Please check all fields again before submitting as there are some missing entries');
		return false;
		}

but this part does not:

if ((document.getstartedform.doyouneed[0].checked == false ) && ( document.getstartedform.doyouneed[1].checked == false ) && ( document.getstartedform.doyouneed[2].checked == false ) && ( document.getstartedform.doyouneed[3].checked == false ))
        {
         alert ( "Please register your type of need" );
         return false;
        }

the top one is for a text field. the botton one is for a checkbox (i assume it can work for a radio button or checkbox) or radio button. either way it doesnt work at all. can someone adjust this so they both work?

Since this is a PHP forum, your question would probably be better served at a different forum that is primarily JavaScript... You may try posting this in the Echo Lounge or something like that, but you will generally get better help with the right knowledge base of people.
