bump

stolzyboy

might be nice if you let us know what line 14 is

sumday

Line 14 is :

if ($_POST['inn'] == "stay") {

Hope this helps.

Don't bump your posts, especially after only an hour

use

 tags for your code -- easier to read.
[*]Tell us what line 14 is
[*]Don't just post your entire application and expect us to go wading through it
[*]There is no "problem."  "Undefined Index" means that the array index (in this case $_POST['inn']) doesn't exist.  Since you are testing for the existence of this variable, it's ok.
[*]The real "problem" is that you have error_reporting set to E_ALL in your php.ini file.  That means that notices will appear.  Ideally, you should code your page so that it never reports notices.  In this case, use [man]array_key_exists[/man].  If you want to be lazy, then turn off notices: [man]error_reporting[/man] (E_ALL ^ E_NOTICE);[/list]

this line

print"<form name=\"inn\" method=\"post\" name=\"inn\" >

should look more like below, and i like echo better

echo "<form name=\"inn\" method=\"post\" action=\"" . $_SERVER['PHP_SELF'] ."\">

In fact, I would rewrite your if statement too. Put your values in an array, and voila! Reduced redundancy! (Notice the use the of the phpBB tag [php] to make this more readable:

<?php
  session_start();
  // -- put the following lines in a DBBerone.inc 
  // -- file, and use include().  that way, you only
  // -- have to edit this information in one place.
      $db_user = 'Berone'; 
      $db_pass = 'moltres'; 

  $connection = mysql_connect('localhost', $db_user, 
    $db_pass) or die(mysql_error()); 
  mysql_select_db('Berone', $connection) or 
    die(mysql_error()); 
  // -----------------------------------------------
  $levels = array(0, 25, 50, 75, 125, 125, 170, 220, 260, 300, 400);
  if ($_POST['inn'] == "stay") { 
    if ($gold >= $levels[$Level]) { 
      $gold = $gold -25; 
      mysql_query( "UPDATE users SET gold = '$gold' where user_name='$user_name'" ); 
      echo "Thank you $user_name for staying at the inn.<br>"; 
    } else { 
      echo "You do not have enough gold to stay at the inn!<br>";
    } 
  } 
  if ($Level == 1) { 
    echo "In your hand you have $gold gold.<br>"; 
    echo "You can stay at the inn for 25 gold."; 
  }
  $php_self = $_SERVER['PHP_SELF'];
