JavaScript PHP and Form submit

Can the Form / Submit get confused?

My opening form line is

<?php
if (!IsSet($stage))
{
?>

<form method="POST" action="<?php print("$PHP_SELF"); ?>" onSubmit="return FrontPage_Form1_Validator(this)" name="FrontPage_Form1">

..... bunch of stuff ..............

<input type="hidden" NAME="Stage" Value=1>
<input type="submit" value=" Let's check to see what this looks like. " name="Submit" tabindex="25"><input type="reset" value="Reset the form" name="B2"></p>
</form>

<!-- now ends the first and begins the next stage -->
<?php
}
elseif($Stage == 1)
{
?>

Here's how your listing will appear:
<table>

<tr><TD colspan="2" ><u> <$php print($Event_Month." ". $Event_Date); ?> </u> - <$php print("$Start_Hour"); ?>:<$php $print("$Start_Minute "); ?> <$php print("$Start_Am_Pm"); ?> - <$php if ($Finish_Hour !=" ") print("$Finish_Hour"); ?>:<$php if ($Finish_Minute !=" ") $print("$Finish_Minute"); ?>" "<$php if ($Finish_Am_Pm" !=" ") print("$Finish_Am_Pm"); ?> </TD> </tr>


This was taken from my form (which works) and sends a cgimail to my e-mail.

I'm rying to expand my horizons I want to move the form to PHP/MySQL but at present I get the form back but it skips the JavaScript validation. (The feedback filling of the form doesn't work either, but one problem at a time)

Any obvious hints?

In your FORM's onsubmit handler I see a call to the function 'FrontPage_Form1_Validator()', but I don't see the function.

Thanks, but that is at the top of the page....

<script Language="JavaScript"><!--

function FrontPage_Form1_Validator(theForm)
{
monthChoice = theForm.Event_Month.selectedIndex
if (theForm.Event_Month.options[monthChoice].value == "")
{
alert("Please pick the month for the event.");
theForm.Event_Month.focus();
return (false);
}

etc...................

What I am trying to achive is the cycle of post thread...preview ... submit that this forum uses, together with a javaScript field checking
