I got this issue where Price is not updated when checking the custom options (Fixed Price: +400).

I got this error:

TypeError: Product.OptionsPrice is not a constructor

TypeError: optionsPrice is undefined

error in custom options price not updated

Update product custom option price on product price change


It happened to me after upgrading to magento 1.9.3.
In my custom theme was missing product_options.js call.

You need to add

<action method="addJs"><script>varien/product_options.js</script></action>

Check catalog.xml and configurableswatches.xml in rwd theme for reference. You will also need to copy




Hope can help

  • Thanks this fixed the error message in console but still it doesn't change/update the price when checking it. Any idea? – nhinzky Oct 14 '16 at 11:53
  • @nhinzky as i said it works for me in Magento 1.9.3. What I noticed that it was only update product-price-id class not product-price-id_clone. I solved this by changing 'idSuffix' => '' with 'idSuffix' => '_clone' in app\code\core\Mage\Catalog\Helper\Product\Type\Composite.php line 130 – krybbio Oct 14 '16 at 21:14
