Formsubmission not working

   <input type="submit" name="Submit" value="  Send  " onclick="self.close()" 

My website has a subscription form ( http://www.ozunited.info/subscribe.htm ) that works perfectly with Internet Explorer. But it does not work at all with Firefox. The form includes java 'self-close' code [ <nowiki><p align="center"></nowiki> <nowiki><input type="submit" name="Submit" value=" Send " onclick="self.close()" </nowiki> Also in the site is a contact form ( http://www.ozunited.info/contactusform2.htm ) that also has the same self-close code. This form also works perfectly in I.E. but not with Firefox. Note that the two forms have different mailit destinations. One is located in an 'in site' folder, the other on an outside server. neaithe work via Firefox What to do? Thanks, Peter
