ARGHHH!!! POST variable problem

I can click links and they work but when I enter data in a form and try to send it to the next php script to process the data, nothing happens. Is there a simple way I can see what is returning from the browser to see if what I expect is actually getting there?? I think $_SERVER['QUERY_STRING'] should do it but I get nothing with that one... Any help is GREATLY appreciated. Robin E. Kopetzky Black Mesa Computers/Internet Services www.blackmesa-isp.net
