launching new window in flash BUT with some stupid cgi script

[aryastarks]

am trying to launch a new window from flash. my script in flash goes like this (it's a registration form within Flash so there's quite a bit of scripting but shown here is just the last 2 lines):
=====================================================
xredirectx= "

http://www.oldcurio.com";

getURL("

http://www.oldcurio.com/cgi/subform.cgi",

0, "POST"
=====================================================

i need to launch a fixed size window when the user clicks on the button in the flash file.

how do i do that?

SOS!
