Need help badly; posting var using a jscommand

is there a way to post a message field variable with the jscommand?

var jscommand:String = “window.open(‘file.php?message=message’,‘win’,‘height=200,width=300,toolbar=no,scrollbars=yes, resizable=no’);”; getURL(“javascript:” + jscommand + “, void();”);

i’ve tried to put this somewhere >> ‘_blank’, ‘GET’ << to no avail.

please help? thi s was supposed to be done yesterday…

thanks
