You will get errors the first time you go to the page because the $_REQUEST array values are not set. Always check that values are set.

Also, this form is not secure. A user can pass HTML to the form to inject code into the page. Always filter and validate all input.

<?php
$number= isset($_REQUEST['number']) ? $_REQUEST['number'] : '';
$op= isset($_REQUEST['op']) ? $_REQUEST['op'] : '';
$amount= isset($_REQUEST['amount']) ? $_REQUEST['amount'] : '';
?>

What happens when you submit the form? You don't have an action URL or a submit button in the form. You could also wrap the code that creates the link in an if() to only show that if the form is submitted (check HTTP METHOD)

The submit field may not be sent if the user uses the Enter key to submit the form. Instead, check $_SERVER['REQUEST_METHOD'] == 'POST'
