  1. Hi All, I have a script that relies on a numeric variable from GET. I am trying to figure out how to have a 'default' value if no GET value is passed in the url. I have been trying to get it to work with if() but no joy: $par2 = $_GET['par1']; if(empty($par2)) { $par = 4; } $par = $par2; So if a value for 'par1' is passed in the url then $par will be whatever that value is. However if no value is passed then the default value for $par should be 4. Unfortunately that code doesn't seem to work. If i pass no 'par1' value in the url i jest get a php error. Any tips on where im going wrong here would be much appreciated. Thanks in advance for any help, Matt
