One error message by submit button on long form

Question

I've done this before, but I don't remember what I did. I
have a very long form with some spry validation. I want to make it
so when the user goes to click submit at the bottom of the form,
they get ONE error message for all text field validation failures.
I do not want to display an additional error message for EVERY
field I have. I just want to display one message saying something
like "You are missing fields" and they can scroll up to find out
which ones. Is this possible?

Sorry I pasted the wrong url. I meant the example
http://labs.adobe.com/technologies/spry/samples/validationwidgets/TextfieldValidationSampl e.html
at the bottom of the page.It should be changed a litte bit to this:
<form id="form9" name="form9" method="get"
action="TextfieldValidationSample.html">
<table border="0">
<tr>
<td>Integer:</td>
<td style="width: 600px;">
<span id="int_min_max2">
<input type="text" name="textfield9" id="textfield9"
/>(Between 100 and 999)
</span>
</td>
</tr>
<tr>
<td>Errors:</td>
<td style="width: 600px;">
<span id="additionalErrorZone">
<span class="textfieldRequiredMsg">You have an
error!</span>
<span class="textfieldInvalidFormatMsg">You have an
error!</span>
<span class="textfieldMinValueMsg">You have an
error!</span>
<span class="textfieldMaxValueMsg">You have an
error!</span>
</span>
</td>
</tr>
<tr>
<td> </td>
<td>
<input type="submit" name="submit9" id="submit9"
value="Submit" />
</td>
</tr>
</table>
</form>
<script type="text/javascript">
<!--
var InvalidZones = new
Spry.Widget.ValidationTextField("int_min_max2", "integer",
{minValue:100, maxValue:999, useCharacterMasking:false,
validateOn:["blur", "change"], additionalError:
'additionalErrorZone'});
//-->
</script>
