inline PHP stopped working with if function and javascript

I’ve had a wordrpress site working for about 2 years using a pluggin called Inline PHP. This is a shortened version that used to work:

<exec>
  $levels = array('Level 3','Level 1','Level 2');
  if (in_array("Level 3", $levels)) {
    echo "<script language=javascript>getlevel('http://www.my-site.com/my-training/level-3/')</script>";
  }
</exec>

This no longer works, and I can’t figure out why.

I’ve tried each component individually:

<exec>
  $levels = array('Level 3','Level 1','Level 2');
  echo implode(' ', $levels);
</exec> 

writes the correct array entries, and

<exec>
  $levels = array('Level 3','Level 1','Level 2');
  if (in_array("Level 3", $levels)) {
echo "yes";
</exec>

returns ‘yes’ (and no if I make the conditional fail), and finally:

<exec>
  echo "<script language=javascript>getlevel('http://www.my-site.com/my-training/level-3/')</script>";
</exec>

redirects to the level-3 page as expected..

The problem seems to be when I am nesting the javascript in the if conditional and it’s just staying on that page – and not rendering anything on the page.

ANY help, would be greatly appreciated
