Passing HTML form and hidden variables from flash to html page


I have a html/flash site now,

i access email from my site itself by giving the userid and pwd text box which i copied from the actual website hosting my email access. i copied the entire
<form…></form> tag to my page and thus was able to put the name and pwd in my home page only and access the email in a separate window.

now i have redesigned my webpage using only flash. i would like to know how i can implement the same using flash. as i have not much experience using action scripting i am a bit stuck about how you pass the hidden form variables. the below is the the exact form syntax:

<form name=“form1” action=“” method=post>
<input type=“hidden” name=sid value=“E9697301F704A0CE947DEF42CF86636A”>
<input type=text size=15 name=f_user value="">
<input type=hidden name=six value=0>
<input type=password size=15 name=“f_pass”>
<input type=submit name=submit value=“Login >>” class=“button”>

how do i implement the above using action scripting. thanks.
