The database connection needs to be made before you can use mysql_real_escape_string().

http://php.net/manual/en/function.mysql-real-escape-string.php

 

Also, there is a syntax error here:

$result = mysql_query("SELECT * FROM predict WHERE first = '$first' AND second = '$second'");
or die ("Failed to query database".mysql_error());
 
There shouldn't be a semi-colon before "or".
$result = mysql_query("SELECT * FROM predict WHERE first = '$first' AND second = '$second'") 
or die ("Failed to query database".mysql_error());
 
 
And in case you're not aware, mysql_* functions have been deprecated and will be removed in PHP 7. More information can be found here:
