How do i do that? i know my code is little messy....please help...please let me know, if u need more details.

function Test()
{
if((screenname=="undefined")||(screenname==""))
{
window.external.Container.SignOn();
window.alert(g_oAAMObject.currentState);
screenname=g_oAAMObject.screenName;
if(g_oAAMObject.currentState=="signed_on")
{
//window.alert(g_oAAMObject.currentState);
screenname = window.external.Container.GetBrowserSN();

}
}else
{

I think you should really be doing this server-side with ASP.Net or PHP or something... JavaScript should pretty much only be used to simplify things for the user, like validating form fields before form submission, hiding unneeded form fields, et cetera. If your page relies on JavaScript to be displayed properly that usually isn't a good thing.

It is a good habbit to double the javascript validate code with a server-side similar validate filter. User may have disable his javascript or he may try to overpass the javascript codes for malicious purposes.
