Hi,
firstly, make you form tag like this:
<form name="frm1" onsubmit="eval_form()">
now, name all fields like this:
<input type="text" name="credit_card">
under <script lang="jscript"> tag, put function like this:
function eval_form()
{
if not document.frm1.credit_card==""()
{
frm1.submit
}
}
You may write any code you like here.
there could be some script err.
