[jQuery] How to solve this

[Johny]

I have a form

<form method="post" action="MyURL" enctype="multipart/form-data">
  <input type="hidden" name="token" value="12"/>
     <p><input type="submit" value="Go"></p>
</form>

The form uploads a large file so that I would like to inform a user to
wait, after he pushes the submit button.

So I have
...
...

        $('[EMAIL PROTECTED]').click(function() {
         $('#InformUserText').show();

                 return false;
         });

....
....

The text ( see InformUserText) is shown but the action script from the
form, see MyURL, is not called.
Can you please help how to say to a user that he should wait and the
script is running?
Thank you
Lad.
