Have you had trouble with loading correctly a challenge?

I'm having trouble with the challenge task 4 of 7 of "listing inventory items":

The paragraph in the HTML displays the number of flavors the store sells, but right now it always shows 2. Change the echo command in that paragraph to display the number of elements in the array.

It keeps showing an error and I can't even preview the result.

Has it happened to you?

None of the steps of this challenge would show in preview for me either, but previous challenges in this course did work with preview. It'd be great if this could be fixed for future users.

<ul>
    <li><?php echo $flavor1; ?></li>

Thanks Preston,

I'm not having trouble with the code. I just mean I couldn't preview anything and don't know if that happens sometimes. The code was:

<?php

$flavors = array("Chocolate", "Vanilla", "Mint");

?> <p>Welcome to Ye Olde Ice Cream Shoppe. We sell <?php echo count ($flavors); ?> flavors of ice cream.</p>
