I have a form that i am trying to submit after the page loads and 5 seconds has gone passed.. i have tried setTimeout but it doesnt appear to be working.. can anyone suggest why this would be the case, i have jQuery on the site but couldnt get delay() working either

<form action= name=cartCheckout id=cartCheckout method=post> 

<input type=hidden name=action value=checkout />

<input type=hidden name=save value=1 />

<input type=hidden name=orderID value=<?php echo $GLOBALS['CHECKOUT_ORDERID']; ?> />



<div class=itembox id=step4box>

    <div id=progress>

        <ul>

        <li>Your Cart</li>

        <li>Your Details</li>

        <li class=current>Payment</li>

        <li>Confirmation</li>

        </ul>

    </div>

<div id=words class=gothbold>Please wait while we we redirect you to<br />Paypal for a secure payment method.</div>



<a class=redirect href=javascript:void(0) title=Proceed to Paypal onClick=document.cartCheckout.submit();><span>If you aren't redirected in 5 seconds click here</span></a><br />



<a class=cancel href=javascript:void(0) title=Return to details onClick=jQuery('#step4box').hide();jQuery('#step2box').show();><span>Cancel</span></a>    

</div> 

<script type=text/javascript>

    window.onload=function(){ 

        window.setTimeout(document.cartCheckout.submit(), 5000);

    };

</script>

</form>     

any help would be greatly appreciated, thanks in advance

EDIT:

changed to this via a combination of @Alex, @user824294 and this question: How Can I create A 5 second Countdown timer with jquery that ends with a login popup?. Now working great and with great functionality of a countdown. Thanks guys!

window.onload=function(){ 

    var counter = 5;

    var interval = setInterval(function() {

        counter--;

        $(#seconds).text(counter);

        if (counter == 0) {

            redirect();

            clearInterval(interval);

        }

    }, 1000);



};



function redirect() {

    document.checkout_paypal.submit();

}
