Hi Domnick,

I see a couple lines that are not escaping quotes. If we want to nest double-quotes inside double-quotes, we have to escape them. Or we can use single-quotes to wrap the whole string, then we don't need to escape the double-quotes.

<?php

$myString = "fish sauce, \"implying\" yummy!";

// or

$myString = 'fish sauce, "implying" yummy!';

?>

There is, however, a difference between strings with single-quotes and strings with double-quotes. This gets into interpolation which I think is explained well here.

As for the fix, here are the lines I noticed:

// before fix
<li class="shirts <?php if ($section == "shirts") { echo "on"; } ?>"> <a href="shirts.php"> Shirts </a> </li>
<li class="contact <?php if ($section == "contact") { echo "on"; } ?>"> <a href="contact.php"> Contact </a> </li>

// after fix
<li class='shirts <?php if ($section == "shirts") { echo "on"; } ?>'> <a href="shirts.php"> Shirts </a> </li>
<li class='contact <?php if ($section == "contact") { echo "on"; } ?>'> <a href="contact.php"> Contact </a> </li>

Hope this helps,

Cheers
