Notice: Undefined index: name in C:xampphtdocs

Hello experts,
I am running with an app and i have some notice error while inserting records.
My form code is pasted below:

[code=html]
<form action=”add_bk_insert.php”>

Name <input type=”text” name=”name”/><br />
E-mail <input type=”text” name=”email” /><br />
Contact <input type=”text” name=”contact” /><br />
Requirement <input type=”text” name=”requirement” /><br />

<input type=”submit” value=”Submit” />

</form>
[/code]

and my add_bk_insert.php code is as shown below:

[code=php]
<?php

mysql_connect(“localhost”,”root”,””);

mysql_select_db(“test”);

$order = “INSERT INTO sal2

(name,email_id, contact,requirement)

VALUES

(‘$_POST[name]’,’$_POST[email_id]’,’$_POST[contact]’,’$_POST[requirement]’)”;

$result = mysql_query($order);

if($result){

echo “Inserted”;
//include_once(“testimonials.php”);
} else{

echo(“<br>Input data is fail”);

}

?>
[/code]

when i run the above code it shows a notice error as below:

[code=html]

Notice: Undefined index: name

Notice: Undefined index: email_id

Notice: Undefined index: contact

Notice: Undefined index: requirement

[/code]
