Mangento Customer Options Change Product Price to 0

I upgraded from Mangento to (manually upgrading each version via SSH, no force upgrade commands). Once I set up with my new theme I noticed something strange. Every product that had a customer option kept changing the product price to zero when the option was selected. Since the site is a clothing store, the majority of the products contain custom options for the purpose of size or color selection. For example a Brand X t-shirt available in colors blue or white and in size S, M, or L.

I read dozens of forums, posts and knowledge base articles about this issue. Many people are experiencing it but very few have the answer, especially for

This is the actual article I used to solve the problem:

However, I could not find the line of code in line 141, for me it ended up being around line 126. Also I could not search the document by copy and pasting this example because the code was broken up differentially when I opened in Coda 2 than it is displayed in this article.

Here’s the instructions I followed to fix the issue:

Custom Options Change Price to Zero in Magento 1.7

After an upgrade to the latest version of Magento – time of writing 1.7, we noticed that the custom options selection was changing the price to zeros instead of updating them.

Turned out there was a bug in the options.phtml file of the current theme – and suprisingly on the base/default too.

To fix the problem

Locate the file: in app/design/[your package]/[your_theme]/template/catalog/product/view/options.phtml on around line 141

Then change

if (this.config[optionId][selectOption.value]) {
   price += parseFloat(this.config[optionId][selectOption.value]);


if (this.config[optionId][selectOption.value]) {
   price += parseFloat(this.config[optionId][selectOption.value].priceValue);


If your theme has this line instead

   price += parseFloat(this.config[optionId][element.getValue()]);

Change it to:

   price += parseFloat(config[optionId][element.getValue().price]);

Someone also posted this solution on Magento Forum

Overall this was an easy fix, but I’m really surprised at how difficult it was for me to hunt down a real solution given that millions of online stores run on Magento. With that said, I’m even more supervised at how many developers have run into this same issue.
