well... unforunatly confirm boxes only come with two buttons, OK and Cancel, but surely "Modify" and "Cancel" would do the same thing... return the user to the form?
heres what i would do:
<script language="javascript" type="text/javascript">
function areYouSure(formName) {
continue=confirm('Are you sure?')
if (continue) {
document.formName.sumbit();
return false
}
else {
return false
}
};
</script>
<form name="theForm" onsubmit="areYouSure(this)" method="post" action="SomeAction.cgi">
<!-- all the rest of your form here -->
<input type="submit">
</form>
does this help?
happy coding
