function not called from onsubmit code

[Steve Brecher]

I have some code comprising the onsubmit attrribute of a form. The code is
executing, but apparently a function called as the last statement is not
executed. The form content is submitted to the server. The behavior is the
same in Firefox and IE (current Windows versions). The following is
excerpted from the browser's "View source":

<script type="text/javascript">
function verify(f)
{
var msg;
var empty_fields = "";
var unselected = "";
var selected = 0;
alert('In verify()'); // not executed
// ...
}
</script>

<form name="ccform" id="ccform" method="post" action="/admin/index.php"
onsubmit="
alert('In onsubmit 1'); // executed
this.type.oneRequired = true;
this.donationtype.oneRequired = true;
this.fname.required = true;
this.lname.required = true;
this.email.required = true;
alert('In onsubmit 2'); // executed
return verify(this);
">

<form name="ccform" id="ccform" method="post"
action="/admin/index.php"
onsubmit="
alert('In onsubmit 1'); // executed

It fails in these 5 lines below

this.type.oneRequired = true;
this.donationtype.oneRequired = true;
this.fname.required = true;
this.lname.required = true;
this.email.required = true;

or, deleting them the 3rd alert is shown.

alert('In onsubmit 2'); // executed
return verify(this);
">

<input type=submit>
</form>

var selected = 0;
alert('In verify()'); // not executed

None of these lines can fail.

You have omitted lines here. If one of these lines has a syntax
error, then the entire function declaration fails, and no function
named "verify" is available to be called later.

What errors does the javascript console show?

It shows a syntax error. Thanks! (Obviously I'm inexperienced with js.)
