Problem getting function to return false

[FunkHouse9]

I have 2 functions, the first one, "GetSelectedIte m" is determining which radio button was selected and running the "formvalidation " function if needed. This is working fine. My problem is getting the entire form to return false if "formvalidation " is false. I can't figure out how to have "GetSelectedIte m" return false if "formvalidation " is false. I've tried a bunch of methods I've found, but I keep getting it wrong.

Any help would be greatly appreciated! Here is what I have:


<script language="JavaS cript" type="text/JavaScript"><!--

function GetSelectedItem () {
chosen = ""
len = document.form.i tem_LabelShip.l ength
for (i = 0; i <len; i++) {
if (document.form. item_LabelShip[i].checked) {
chosen = document.form.i tem_LabelShip[i].id
}
}
if (chosen == "ExpressShi p") {formvalidation (this)}
}



function formvalidation( )
{
with (document.form. ShipperAcctNumb er)
{
if (value == null || value == "")
{alert("For overnight FedEx/DHL shipping, you must enter an account number.");retur n false}
else {return true}
}
}


//--></script><form name="form" onsubmit="retur n GetSelectedItem ()" action="http://www.cartserver. com/sc/cart.cgi" method="post">

if (chosen == "ExpressShi p") {formvalidation (this)}

if (chosen == "ExpressShi p") { return formvalidation( this); }
