  1. Well thanks hopefully this help any other noob like me fail at ajax this is just an ajax test actually I'm more of a php developer so I'm testing myself in new areas....I know its sloppy right lol
  2. Yes, I just figure it out I didn't return x is there any way I can close this out ?
  3. I've been following this tutorial on how to use ajax I have to admit I'm new at it. I could use jquery but I hate it. I would like to know if someone can help me figure out why my code is reading Uncaught TypeError: Cannot set property 'onreadystatechange' of undefined. when I fire off the Friend request button or block button. ? <?php error_reporting(E_ALL);
