Alert message showing twice in IE

Hell all,

I have used a javascript popup form, with javascript validation. The form seems to work fine as far as validation and submission is concerned in all the browsers.
But, the problem comes when we try to submit the form in IE. Validation works and form also gets submitted, but after the form gets submitted, the alert message is shown twice in IE, also the whole page gets disturbed.

one can refer the link: http://masterworks.in/sportybeans/index.php
the form appears when one clicks over 'Enroll Now, image/icon.

what can be the error i am not getting…

I’m also getting an error in my IE (it has show errors turned on) that stems from the following code:


fg_hideform('fg_formContainer','fg_backgroundpopup');

Because there is no element on the page with an id of ‘fg_formContainer’
