i have a form which have 45 input boxes, i applied jquery validation for all input boxes , but there is two pair of input boxes which have either oneof them should be filled up, not both. so how do i change jquery so that if anyone fill up first pair then jquery does not check second pair of input box and if any one is fill up second pair then not check for fisrt one's and also i have used radio box for showing one pair at a time

i show code below:

jQuery Code

<script type="text/javascript">
$j=jQuery.noConflict();
    $j(document).ready(function()
    {
        function validate() {
        return $j("input:text,textarea,select,radio").removeClass('rdb').filter(function() {
        return !/\S+/.test($j(this).val());
         }).addClass('rdb').size() == 0;
    }
    $j('#myForm').submit(validate); 
    $j(":input:text,textarea,select").blur(function() {
    if(this.value.length > 0) {
        $j(this).removeClass('rdb');
    }
    });
    $j("input:radio").click(function(){
        if($j(this).val()=='o'){
            $j("#rcpt").css("display","none");
            $j("#notRcpt").css("display","inline");         
        }
        if($j(this).val()=='r'){
            $j("#notRcpt").css("display","none");
            $j("#rcpt").css("display","inline");            
        }
    });
}); 
</script>

PHP Code

<form name="myForm" action="somepage.php" method="post" id="myForm">
<table width="100%" border="0" cellspacing="4" cellpadding="0">
    <tr>
       <td class="boxtitle">Delivery Pick up Station/Place</td>
    <tr>
        <td style="font:bold 11px verdana;"> 
            <input type="radio" name="receipt" value="r" >Receipt
            <input type="radio" name="receipt" value="o" >Other 
        </td>
    </tr>
    <tr>
        <td>
           <table width="100%" border="0" cellspacing="3" cellpadding="0">
           <tr id="rcpt" style="display:none">
                <td width="12%" align="left">Receipt:</td>
                <td width="30%" align="left"<input type="text" name="deliveryNo" id="deliveryNo" /></td>
                <td width="25%" align="right">Pick up Date:</td>
                <td width="35%" align="left"><input name="deliveryDate" type="text" id="deliveryDate" /></td>
           </tr>                            
           <tr id="notRcpt" style="display:none">
                <td>Other:</td>
                <td><input name="deliveryNo" type="text" id="deliveryNo" /></td>
                <td align="right">Pick up Date:</td>
                <td><input name="otherDeliveryDate" type="text" id="otherDeliveryDate" /></td>
