I have this piece of code

```
<?php

$con = mysql_connect("localhost","root","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("tables", $con);
$sql="INSERT INTO customer (Name, Telephone, Email, Address, PostCode, Specialisation )
VALUES
($_POST['firstname'], $_POST['telephone'],$_POST['email'],         $_POST['address'],$_POST['postcode'],$_POST['special'])";

if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
} 
echo "Inserted into Worker database";

mysql_close($con);
?>

```

I keep getting this error- Parse error: syntax error, unexpected T\_ENCAPSED\_AND\_WHITESPACE, expecting T\_STRING or T\_VARIABLE or T\_NUM\_STRING in. 

I am not sure what else to do. Please help. Thanks
