To expand on Jay's excellent advice, you have been depending on "register globals" to set the variable names for you. This is widely regarded as a bad practice, because you don't know for sure where $var came from. You should ALWAYS use $var=$_GET['var'] when taking values from the url to set a variable. For more information on the evils of register globals, STFA. There have been many discussions in this list on that topic.
