Getting 2 Notice: Undefined Variable errors - undefined

Question

The two errors are as below:
Notice: Undefined variable: HawA_Homes in C:\wamp\www\HawA_CIS241\InsertRecord.php on line 48
Notice: Undefined variable: HawA_Homes in C:\wamp\www\HawA_CIS241\InsertRecord.php on line 56
I've checked my names and they appear correct and I am not sure how to proceed now.
Code is as below:
<?php
$hostName = "localhost";
$databaseName = "test";
$userName = "root";
$password = "";
$tableName = "HawA_Homes";
//try to connect report error if cannot
$db = new mysqli($hostName, $userName, $password, $databaseName) or die(" Could not connect:" . mysql_error());
print(" Connection successful to host $hostName <br /> <br />"); //report connection success
//Get data to create a new record
$Address = $_REQUEST["address"];
$DateBuilt = $_REQUEST["dateBuilt"];
$Value = $_REQUEST["value"];
$Size = $_REQUEST["size"];
$Number_of_floors = $_REQUEST["floors"];
$sql = "INSERT INTO $HawA_Homes('Address','DateBuilt','Value','Size','Number_of_floors')VALUES{'$Address','$DateBuilt','$Value','$Size','$Number_of_floors')"; //Create insert query for new record
//try to query dataase / store returned results and report error if not successful
if(!$result =$db->query($sql))
{
//die('There was an error running the query[' .$db->error . ']';
}
print("SQL query $sql successful to database: $HawA_Homes <br /><br />"); //report sql query successful.
?>

Answer 1

You have these notices because the variable $HawA_Homes isn't declared in your code before being used at line 48 and 56. (These are just notices, they are not critical errors, you can avoid displaying them by adding error_reporting(E_ALL & ~E_NOTICE); at the begining of your code, like explained here)
In fact, you used $HawA_Homes instead of $tableName in these lines. Replace them, you won't have notices anymore for these lines.
