Why does my variants price doesn't change shopify

[Jackypotato]

I have variant of necklace : size 
Large : $ 375 
Small : $ 249 

and for sure I have saved it many times 

and when it goes to the website 
https://tanchur.com/products/auspicious-heart-lock-necklace?variant=42934170058822

the price doesn't change with the variant  

the price keep $375 even I click on small 

could anyone how to fix it ?

Just want to confirm did you add a custom JavsScript in the global.js file?

Because I click on the variants it show the issue in the Console.

Based on confirmation I can provide you better solution.

Thanks

nope i didnt change any on global.js file . 
I'm trying to revise on  " snippets > price.liquid "

Could you please share the price.liquid code so that I check if there is any issue.

Hi there , still doesnt work .. either i choose large or small , still $375. 
i find that mainly due to the theme .. 
now I'm using my own theme , i uploaded my self  

shrine-pro-custom-theme 

I find that the issue maybe due to this theme.. 
how i can fix it  ?  

i can send u the script of my theme if you needed . 
when I change to other theme , like dawn , no problem at all. 

so how I need to fix it ? 

[Jackypotato]

Thanks Jignesh ， i find an alternative .. i change to the theme Dawn , which can fit me .. and variant price works well on that page

Go to Online Store > Edit Code.
Under Sections, open product-template.liquid or main-product.liquid.
Look for the price code.
Make sure it's using {{ current_variant.price | money }} or JavaScript that updates price on variant change.
Save and preview. 

[Jackypotato]

Hi there , didnt see such code , but find the following : 

 "product.selected_or_first_available_variant.price | money"

[Ecom_boss-]

@Jackypotato 
Can you see this code?

{{ product.price | money }}

If yes, replace it with this code

{{ current_variant.price | money }}
