Two Reloads, with output after input?

[Thumbz]

After inputing my email and password  and clicking submit, the echo in Verify_User (in bold) doesn't show up, nor does it load the logged in form of the log in bar.  If I reload the page or press submit again (even without entering any information), everything works.  At first I though I might just be outputting before getting my input on the reload, but all info is obtained at the top.  I also thought it might be $logoff, but it doesn't tell me "You logged off!", while still setting $logoff to true by the end in order to output the login menu.  Therefore, it get's passed if($Logoff) but doesn't make it to Verify_user, so for some reason $L_Email and $L_Password aren't set after the first refresh.  I'm a newbie so any help, related to the problem or not, would be greatly appreciated.

P.S.  The logoff button works the first time.

 

 

<?php
$L_Email = $_POST['l_email'];

//if the page was requested with an effort to logoff
if ($Logoff)

  //setcookie("session_email", "", time()-3600);
  setcookie("session_password", "", time()-3600);

//if logging in, Email and password are already set, make them cookies
else if($L_Email && $L_Password)

  setcookie("session_email", $L_Email, 0); 
  setcookie("session_password", $L_Password, 0);
