Variant prices not changing with different size selections on manually entered inventory

Technical Q&A

Topic summary

A user encountered an issue where variant prices weren’t updating on the product page for two manually entered inventory items, despite being configured correctly in the backend. The price displayed remained at the lowest variant ($5) regardless of size selection, though checkout showed the correct price.

Troubleshooting attempts that failed:

  • Uninstalling a PreSale app
  • Resetting product-template.liquid and product-price.liquid files to defaults

Root cause identified:
The problem occurred because variants lacked assigned images. Products created through third-party apps worked correctly, likely because they had images assigned to each variant or were single-variant products.

Solution provided:
Two options were offered:

  1. Assign an image to each variant
  2. Fix the theme code by uncommenting lines starting at line 642 in assets/theme.js (code that checks if the new variant image is the same as the old one)

Resolution:
The user confirmed the fix worked perfectly after implementing the suggested code change.

It’s the strangest thing. My prices change with the products that I created thru third party apps , but the inventory that I manually entered (quantity, size, prize, inventory count, sku) does not change with the variant.

I set variant sizes with different variant prices-confirmed in Product and Inventory that the prices are different w/each variant, but it only displays the price of the first variant option which is the cheapest price.

Notes:

  • 2 products manually entered/local inventory, all other products are created thru apps.
  • Only those 2 products are having the issue
  • At check out, it will show the correct variant price, but upon selection the price stays $5-lowest-even if someone selects the highest variant.
  • Customers are not seeing the price of their selection until checkout.
  • I installed a PreSale app to create a sales campaign but it did not affect this. It had this issue before. Now the pre-sale app doesnt work with the inventory.
  • I uninstalled the app in hopes it would change/it did not.
  • I reset my product-template.liquid and product-price.liquid files back to original-no change
  • Variant prices do not change with manually entered inventory, only products created thru apps

View of product-template.liquid attached

View of product-price.liquid file below:

{% if product.title %}
{%- assign compare_at_price = product.compare_at_price -%}
{%- assign price = product.price -%}
{%- assign price_varies = product.price_varies -%}
{%- assign available = product.available -%}
{% else %}
{%- assign compare_at_price = 1999 -%}
{%- assign price = 1999 -%}
{%- assign price_varies = false -%}
{%- assign available = true -%}
{% endif %}

{%- assign money_price = price | money -%}

{% if compare_at_price > price %}
{{ ‘products.product.regular_price’ | t }}
{{ compare_at_price | money }}

{{ money_price }}

{% if settings.show_saved_amount and settings.show_discount_amount == ‘money_save’ %}

{% assign sale = product.compare_at_price | minus: product.price | money %}
{{ ‘products.product.on_save_like_price’ | t }} {{sale}}

{% endif %}
{% else %}

{{ ‘products.product.regular_price’ | t }}
{{ money_price }}

{% endif %}

Looks like other products are either single-variant products or each variant has image assigned.

The page you’ve shared fails because variants have no image assigned.

There are 2 options:

  1. assign image to each variant

  2. fix the theme code.

In your assets/theme.js there is this commented code (starting [email removed] line 642):

//       if (
//         !variant.featured_image ||
//         variantImage.src=== currentVariantImage.src
//       ) {
//         return;
//       }

This was a check whether newly selected variant has no image assigned or new image is the same as the old one and skip product image update if this is the case.

My recommendation is to uncomment this code (by removing // at the start of each line) unless you know a good reason why this was done.
