How to autopopulate name of logged in user in field on a form?

[Aditya Sinha]

I have a form where a field needs to be populated with name of logged in user.  I am using an on load script however it is not working, (I have checked the UI type to ALL).

function onLoad() {

   //Type appropriate comment here, and begin script below

   var gq=new GlideRecord("sys_user");

   //alert((g_form.getReference(g_user.userID)));

   var ab=g_user.userID;

   gq.addQuery("user_name",ab);

   gq.query();

   g_form.setValue("field name",gq.name);

}

Hey Sandeep. Can there be a reason for the filed still not getting populated apart from this?

I have copied the field name correctly, however my g_form.setValue("field name",val) command isn't populating my field. I have taken care of the UI and checked it to ALL. Any suggestions are welcome
