In circumstances where you have product swatches enabled and your product variant names have special characters in them (such as quotation marks ("), apostrophes ('), ampersands (&), etc.), the product page may break.  Your product gallery will not show, and choosing options does not update the price as it should.  This is due to a JavaScript error that is caused by these special characters.  This has been corrected in versions 5.0+, but if you're using an older version and have encountered this issue, please follow these steps to fix it:

1. In your Shopify dashboard, click Online Store > Themes and look for the ShowTime theme.

2. Click the the ... button and choose Edit HTML/CSS from the drop-down menu as shown below.

3. Open the Assets folder and locate the scripts.js.liquid file. Click it to open it in the built-in editor.

4. Around line 378, you should see the code below.  If you don't see it around line 378, search the file by hitting Control + F (or CMD + F on a Mac).  Remove it and save the file.

{% if settings.show_product_swatches %}
    // BEGIN SWATCHES
    if (variant) {
      var form = productPanel.find('form'); // find the form in the panel
      for (var i=0,length=variant.options.length; i<length; i++) {
        var radioButton = form.find('.swatch[data-option-index="' + i + '"] :radio[value="' + variant.options[i] +'"]');
        if (radioButton.size()) {
          radioButton.get(0).checked = true;
        }
      }
    }
    // END SWATCHES
    {% endif %}

5. Next, go to the Templates folder and open product.liquid.  Look for this code and remove it:

 {% if settings.show_product_swatches %}
    // BEGIN SWATCHES
    if (variant) {
      var form = jQuery('#' + selector.domIdPrefix).closest('form');
      for (var i=0,length=variant.options.length; i<length; i++) {
        var radioButton = form.find('.swatch[data-option-index="' + i + '"] :radio[value="' + variant.options[i] +'"]');
        if (radioButton.size()) {
          radioButton.get(0).checked = true;
        }
      }
    }
    // END SWATCHES
    {% endif %}

6. Save the file. The issue should now be resolved.
