Products variant's price is not changing on product page.

[htownhemp]

Hello, 

I'm using Minimalin theme and redesigned the website recently. I'm having issue with the variants prices who are not changing. 1st variant price is showing by default. But when we select different it still shows the 1st variant price. It works fine on cart page and checkout, we can see updated prices there. Is there anyone who can help me.

Hi @htownhemp ,

Try refreshing the page while the variant changes:

And wrap them in <script></script> tags

I see the code but where to use and how? I can't see theme.js or custom.js file in the theme code. Thanks

Hi @htownhemp ,

It's possible that you are using a custom theme and there's a coding error. If the variant picker section includes 'variant.price' and your theme is set to 'product.price', this could lead to an error. You can contact us for assistance in fixing this.

I don't have these two codes named with 'variant.price' and 'product.price'
