Undefined index: cash in pset7 at portfolio.php

Question

I'm getting the following error which doesn't allow me to display the portfolio correctly. Could anyone help me to find the issue?

This is the error message: Undefined index: cash in /home/ubuntu/workspace/pset7/views/portfolio.php on line 37

This is line 37:

<tr> <td colspan="4">CASH</td> <?php print("<td>{$_SESSION["cash"]}</td>"); ?> </tr>

Make sure you're calling session_start() and you assigned something to $_SESSION["cash"] previously. It is good practice to first check if it's set before trying to use it:

<?php if( isset($_SESSION["cash"]) ){ ?>
  <tr><td colspan="4">CASH</td><td><?= $_SESSION["cash"] ?></td></tr>
<?php } else { ?>
  <tr><td colspan="5">Unknown CASH amount</td></tr>
<?php } ?>
