[jQuery] How to solve this


I have a form
<form method="post" action="MyURL" enctype="multipart/form-data">
<input type="hidden" name="token" value="12"/>

<input type="submit" value="Go">


</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
...
...
    $('input[@type=submit]').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.
